Nature and Human Will Sink or Swim Together——A review on THE BLUE PLANET from a perspective of post-modernism

In the movie of the blue planet,it suggests that the earth is unique,and human should get along with earth in harmony.And this article uses the view of the Constructive Postmodernism to state the relationship about human and nature.We find that we can't live without the nature.We are not the master of the earth,and we should protect it.We need remain the point that Ecological Civilization and sustainable development.So,human need to coexist to the life in this blue planet,and we contribute power to make our earth more and more beautiful.     

Protecting the Earth

<正>The earth is in trouble now!We need to take measures to protect the environment.Recycling is a great way to save energy,space and money.However,recycling is not the only way to protect the environment.For example,we can save water by taking shorter showers.It is also important for us to use reusable bottles for drinks and have our lunch in reusable bowls.     

软土地基深基坑支护中的土压力

本文通过在软土地基深基坑支护中土压力、孔隙水压力的大量测试,经统计分析、反分析及对比分析,提出了主动土与被动土不同的受力机理,利用朗肯公式计算时,应取土的不同强度指标,即主动土压力计算取固结快剪指标,被动土压力计算取快剪指标。     

基于植物群落的城市设计

城市植物群落是城市绿地的基本构成单位,规模适中、结构合理的城市植物群落健康的发展演替,对于城市生态环境的稳定与改善极为有利。在城市设计中宜根据植物群落对土地面积和土壤、水等的要求,正确利用城市的生境资源,保护并培育城市植物群落,以求高效地改善城市生态环境。在内部空间、外部环境设计中应结合植物群落的生境、城市野生动物的栖息需求以及景观文化来进行相应的处理。     

Living on the Moon

<正>Some people believe that humans could live on the moon in the future.That is because our planet,the earth,is too crowded and polluted.The moon is another ideal place for humans to live in.Scientists will develop plants that can grow on the moon and can produce food,oxygen and water.The gravity on the moon is only oneeighth of that on the earth,so people should wear     

水及土压力的实测研究

通过对上海软土地基基坑工程的实测土压力、实测孔隙水压力值和实测水位值的分析,阐述了基坑外土压力、孔浊水压力随工况的变化规律。认为软土地区既可采用水土合算,又可采用水土分算。给出了水土合算时的侧压力系数的取值方法;同时提出了水土分算时,土压力与水压力应分别乘以相应的系数,且给出了水压力合理的折减系数ｋｗ值（孔隙水压力与静水压力的比值称为静水压力的折减系数）以及水土分算时的土压力项的侧压力项的系数ｋｓ     

ONE UNIVERSITY ONE VILLAGE PROGRAM: PROMOTING ENDOGENOUS DEVELOPMENT IN RURAL AREAS THROUGH LOCAL PRACTICE

This interview is centered on the practice of earth architecture in rural West China, starting from introducing the post-earthquake reconstruction project in Guangming Village, Yunnan Province, as an outstanding example of the practice of the “One University, One Village” Rural Sustainable Development Assistance Program. Li Wan, the interviewee, explains the differences of design consideration and the difficulties in practicing earth architecture throughout China, while giving her prospect on its future application. Through a further introduction on the operation and project procedure of the Program by Wan and her team, the interviewee addresses that architects should take their responsibilities on solving social issues, with a hope that, through their site-based efforts, the Program could provide a global paradigm to similar earth architecture practices in other regions, rousing designers’ awareness of localization.     

圆形盾构隧道水土压力表示与计算半径取值分析

盾构隧道周围的水土压力有投影表示法与径向表示法,两种表示方法的比较分析表明:水压力宜采用径向表示法,当径向表示法转换为投影表示法时,任意点的投影荷载数值与径向表示法时的荷载数值完全相等;土压力宜采用竖向与水平的投影表示法。针对圆形盾构隧道周围的水土压力作用半径与盾构隧道横断面曲梁的中心半径不一致问题,对盾构隧道计算半径的取值方法进行了分析,结果表明:当隧道的计算半径取为外半径时,盾构隧道的内力与变形偏大;当隧道的计算半径取为中心半径时,盾构隧道的内力与变形偏小。从荷载作用效果的等效性角度,分别得到了盾构隧道计算半径不同取值方法对应的水土压力修正系数与曲梁刚度修正系数,并给出了不同荷载对应的盾构隧道计算半径的取值建议。

高压喷射注浆止水帷幕技术在某工程基础施工中的应用

在已有建筑群中的新建建筑物,如地下水丰富,基础施工时为保证已有建筑的安全,是不能进行大量抽水的。这种情况下,只能在基础四周采用止水帷幕措施,一是用来保证基础正常施工;二是用来防止周围地下水不发生大量流失,从而保证周围已有建筑物的安全。文章介绍高压喷射注浆止水帷幕在基础施工中的应用。
