【摘要】 重庆轻轨一号线工程小什字车站位于市区解放碑附近繁华地段,建于砂、泥岩互存地层内。为指导该工程的施工开挖和合理的工程设计,本文通过工程类比及数值计算分析结果表明,围岩是稳定的,并具有较大的潜力。另外,从地层与结构稳定以及保障地面建筑物安全出发,还提出了地表下沉控制标准与相应最大下沉量值等。更多还原

【Abstract】 Xiaoshizi’s station,the first line engineering of Chongqing light railway,is located at the busy area near the centre of city,Liberate Stele,and it will be built in the layer filled with sand and mud-rock.In order to help construct,excavate and resonable design,the engineering analogy and computer analytic results in this paper show that the surrounding rock is stable and has considerable potentialities.Meanwhile,this paper,on the basis of the stability of layer and structure and the security of ground buildings,also presents the control standard of the earth’s surface descend and the relative greatest descend value.更多还原
