【摘要】 进入90年代以来,上海的建(构)筑物迅速向高、大、深、重的方向发展,从而使地下工程的试验、研究、设计、施工和监测,成为上海岩土工程界的主攻方向。在软土地基上进行桩基施工、开挖深基坑和沉井工程,都会对软弱土体产生扰动和破坏,失去稳定性的土体所表现的应力应变复杂过程,随时都会给工程带来危害。上海岩土工程界从众多工程事故实例中取得经验教训,摸索到一套行之有效的办法,对于常见的上海地下工程技术问题,从原理、计算和处理三方面作出论述。更多还原

【Abstract】 Since entering the 1990’s,the architectures and buildings of Shanghai have been developed rapidly towards the state of high,great,deep and heavy and thus,the test,research,design,construction and monitoring for the geotechnical engineerings have become the main direction of research for Shanghai geotechnical engineering circle. Foundation pile constuction ,deep pit excavation and well sinking on soft soil foundation all will produce the disturbance and damage on soft soil body. The soft soil body which lost stability and had presented complicate stress and strain process will bring damage to the project at any time. Shanghai geotechnical engineering circle has obtained experience from plenty of engineering accidents and also found out a set of effective measures to solve the difficult technical problems in the aspects of geotechnical engineering and have achieved a lot in Shanghai urban construction as well. The paper,moreover,would like to elaborate and approach to Shanghai common engineering technical problems in the aspects of its principle,calculation and process with the fellows in the same trade.更多还原
