Join us

It is the first time that I put on a post to say “Hey! Join us, if you are interested in.”

We are doing amazing research here with incredible enthusiasm and broad interests.

There are tons of reasons that people choose to do research; it could be a hobby, or to make a living, or any reason you name it, but my favourite reason is always that you love it. If you love your job, then you will do it with passion and happiness. 996 is never a problem only if you love it. (Well, it doesn’t mean 996 in our team…I never advocate that. See the photo, people played badminton; and we should do it more later on.)

My interests include (but not limited to)

1. Impact of electricity on clay minerals

By applying electric voltage on clay minerals, we look at the variation of its mineral structure and engineering behaviours. This could be a scientific research on clay mineral level (chemical & micro level); it could also be linked to potential engineering application in the area of geotechnical and geoenvironmental engineering.

2. Soil remediation and ground water treatment

This is a research area on removal of pollutants from contaminated soil or protection of ground water. This research topic can be linked to EK technique as well. And another possibility is to use Fe-rich clay minerals as redox materials for ground water treatment.

3. Dewatering and consolidation

This topic is about removal of water from very fine-grained soil, like sludge, slurry, clay, etc. These kinds of materials have very low hydraulic conductivity, but electro-osmosis can be an effective method for dewatering and consolidation of them. We are looking at the challenges of this EO technique in large scale of application.

4. Geosynthetics

We are interested in application of geosynthetics.

1) Reinforcement, which is a very popular application for decades and lots of people from academy and industry are doing it.

2) Filtration and drainage. This topic is related to dewatering and consolidation. One of the special issues that we are especially interested in is the clogging problem of geotextiles. There are lot of things to do, include mechanism of clogging, update of manufacturing and design code, invention of novel types of geotextiles.

3) One more thing about geosynthetics, which is special for our research is EKG. This novel material presents a new category of geosynthetic and I’ve been staying in this topic for over decade.

5. Unsaturated soil, constitutive model and numerical modelling

We are carrying out this research partially also because of EK technique. When applying EK technique, it is related to unsaturated soil and suction. Therefore, we’ve been developing completely new constitutive model and trying to apply it in suction measurement, EK design and also trying to develop code for numerical modelling and software for EK design.

6. Mining, tailing, liquefaction, etc.

More researches that are related to my basic interests previously mentioned are being explored, we will see more ideas and fantastic work coming up.

So…welcome to join us…

And also, any collaboration is welcome.

Looking forward to hearing from you

七月

刚刚看到燕子也唱过这首七月,就是那个流浪的燕子冬天的树那个燕子。
这首歌容畅是原唱,卢中强可能是作者,网上比较多的时候可能是汪蕊,当时毕业季很多人唱,不过那是很久以前的事了,后来用在了爱情呼叫转移中,江映蓉版本。

      那一年的寒风中 / 你化了很浓的妆
      第一次牵我的手啊 / 就装作老练的模样
      你等我说 / 等我说你漂亮
      哦真的我真的很想

      有一年的夜色中 / 我遮住星星的光
      第一次吻我的脸啊 / 多少有些惊慌
      你等我说 / 说你是我唯一的港
      哦真的我真的很想

      七月的无奈 / 我们尽量不去想
      你说你的山 / 我说我的水乡
      七月的无奈 / 我们尽量不去讲
      哦真的也许真的很傻

      Logogogo 评论 数学物理方法

      练乾坤大挪移前学好九阳神功;做论文前学好数学。
      求学时代好好学习数学,毕业之后,数学能够不忘记就很不错了,还能精进的很少了。


       这是我写的第一篇书评(划掉,不是我写的,转的,作者在开头),我从来没有想过,是写给这样的一本书的。这的确是我迄今最仔细读过的一本书。
          在上高一的时候,我就买过一本《数学物理方法》,纯粹出于对书名的崇拜,那还是四川大学出版的那一本。当然,那时的我只能看到Riemann plane就晕得差不多了。那的确是我第一次听说有这样的书存在,数学和物理,好神奇。

      k0

      I didn’t know that k0 proposed by Jozsef Jaky (1944) is an analytical result instead of empirical one. In many text books, even including the ** text book, it is presented as an empirical formula.

      I doubt that few people actually read the reference from Jaky, ‘ause it is in Hungarian. This is very similar to the case of Reuss (1809), which was published in French.

      Nowadays, introduction part of most papers, theses or dissertations, is presented in a way of piling up references without reading any of them. The only purpose is probably to flatter the potential reviewers like “see, I cited your work”.

      For work with strong innovation, please be confident enough to refer to “本文不必参考任何文献”(钱伟长,2002) However, in most cases, the authors 怂ed and cited some references like “土力学教材”、“数理方程课本”, in order to be published.

      “3G” GENERATIONEN-AUSSTELLUNG – FINISSAGE 01. MAI. 2022

      I would like to recommend the “3G” GENERATION EXHIBITION held by my friends. It is from 13th Feb (0:00) to 8th May (0:00) located at Forstmanns.

      (Februar 13) 0:00 – (Mai 8) 0:00 Forstmanns

      I remember very well those days in 2013 when I was at Hattingen with Herbert and his family. There was a beautiful back yard with a cabin full of wine bottles. We were hanging around and wandering in a forest nearby with your Emma (Did I get the correct name?). And 2020, we were in Rhein area-Bad Hönningen-Hattingen-Königswinter, wine and beer beside a castle and vineyard.

      清明

      夜来携手梦同游,晨起盈巾泪莫收。
      漳浦老身三度病,咸阳草树八回秋。
      君埋泉下泥销骨,我寄人间雪满头。
      阿卫韩郎相次去,夜台茫昧得知不。

      鸡汤如酒,可饮不可多饮

      水中花 & 难舍难分

      郁可唯翻唱了谭咏麟的水中花,与之相对应的另一首老歌是难舍难分,曾经的 “十大煽情分手歌曲” 之一;同样的杏花春雨,同样的雨打风飘,年华流走,同样的灯火阑珊,烟消云散。。。
      然而真正使它一度跻身“十大煽情分手歌曲”,恐怕并不是这些叠加的意象 ,而是——“说起来爱情的悲欢离合有个你我永远不提,相偎又相依要留在心底陪我一路到天涯”。——不知道有多少人走过爱情之后会永远留一个人在心底,永不再提,也永不忘记——五百年后剖开自己的心,看到一颗晶莹的泪滴,那里面恍然有一个被泪滴的表面张力球面化了的倩影,不必犹疑,你一定会记得她是谁

      土力学及岩土工程教育与教学

      李广信

      (清华大学水利水电工程系)

      1.历史的回顾
              我国大学中的土力学课程教学大约始于20世纪30年代末期。最早在国内大学开设土力学课程的是黄文熙先生(中央大学)和茅以升先生(唐山工学院)。他们是我国土力学课程的开拓者。而在30年代时,土力学在国际上尚属新兴学科。
              黄文熙先生于1937年在美国密执安大学获得博士学位以后,应南京中央大学邀请回国任教。因学校内迁,1937年末才辗转到达重庆,任中央大学水利系教授和系主任,开设了土力学课程,建立了土力学实验室,是国内首次在大学建立的土工实验室。
              茅以升先生在1938-1941年间,任唐山工学院院长,开设土力学课程,并在全校作“挡土墙上的应力”学术报告。
              此后,陈樑生于1948年在清华大学,俞调梅于40-50年代间分别在上海交通大学和同济大学,钱家欢、曾国熙于1952-1953年在浙江大学,冯国栋于50年代在武汉大学分别开设了土力学课程。
               20世纪50年代我国翻译了一批土力学和基础工程教材(多是译自俄文版)。我国最早中文版土力学教材是在西南联大时期阎振兴编写的《土壤力学》;解放后早期的教材有:丘宝勤编撰,中国科学图书仪器公司1953年出版的《实用土壤力学》;钱家欢编写,由大东书局1953年出版的《土壤力学》;钱家欢与唐念慈合著《基础工程规划与设计》(大东书局1954年出版),陈仲颐编写的《土力学地基与基础工程》(1954年,高教部教材处);由陈樑生和陈仲颐编写,由水利出版社1957年出版的《土力学与地基基础》;吴炳焜等编写的《土力学地基与基础》(高教出版社1958年出版);俞调梅的《土质学与土力学》一书由工业出版社1961年出版。
