摘要
以宁波轨道交通试验段车站深基坑地下连续墙为工程背景,采用抛物线柱体模型对有超载工况地下连续墙的槽壁稳定性进行分析.探讨了护壁泥浆作用下,模型参数对槽段稳定的敏感性及安全系数的影响.结果表明:地下连续墙施工槽段是稳定的.对槽段平面位置、深度和垂直度进行的检测也验证了计算结果的正确性,可为宁波地区类似工程提供理论和实践依据.
Taking the diaphragm wall slurry trench in Ningbo rail transit test section as the study case,the stability of slurry trench with a surcharge using the paracurve cylinder model is analyzed.The influence of model parameters on the sensitivity and the safety factor of slurry trench stability under the protection of slurry wall are discussed.The detection results of plane position,depth and verticality of slurry trench are used to determine the stability of diaphragm wall.Some measures have been successfully applied to the excavation of slurry wall trench,through which the calculation results are validated.It is expected that this research may offer a reliable reference for other similar engineering projects.
