2 . the concept design is the key phase of the first stage of system optimization . the paper emphatically discusses with emphasis several issues difficulty to answer , such as the determination of the soil parameters , the soil pressure and the safety factor and the reliability of retaining structure , summaries and analyses the main geotechnical problems during the excavation on the four familiar geologic strata of saturation soft soil on the class i terrace of the yangtze river , aged - clay , expansive soil and loess and investigates carefully the patterns of deformation and destruction of pit slope in the saturation soft soil , puts forward three basic principles of selecting schemes of retaining structure , namely : facing to the problem , facing to the characteristics of excavation and environment
( 2 )概念设计是深基坑工程第一步优化? ?系统(方案)优化设计中的关键，文中重点讨论了概念设计中的几个难点问题，如土性参数的确定、土压力的选取、深基坑工程的安全度和可靠度分析等；总结分析了饱和软土、老粘性、膨胀土和黄土这四类常见地层条件下的深基坑工程中的主要岩土工程问题，其中重点研究了长江级阶地上的饱和软土深基坑边坡变形和破坏模式，提出了选择支护方案的基本原则，即：面向问题、面向基坑特点、面向周边环境特点。
