摘　　要：综合管沟是一种新型的地下结构,为了更好地了解综合管沟的沉降规律,以深圳市某市政工程综合管沟的大量监测数据为基础,应用仿真软件ABAQUS对综合管沟的沉降进行数值模拟分析,通过模拟沉降值和实测沉降值对比分析,验证了模拟分析的可行性。工程实践证明,采用的沉降模拟模型分析精度较高,能满足预测综合管沟沉降的需要,可为综合管沟的沉降分析提供一些科学依据。Utility pipe is a new type of underground structure. In order to better understand the settlement rule of pipe,this paper,based on a large amount of monitoring data integrated trench of a municipal engineering of Shenzhen city,uses simulation software ABAQUS to simulate the pipe settlement,and compares analysis of simulated sedimentation and measured subsidence values,which verifies the feasibility of the simulation. The engineering application shows that： the simulation accuracy of this settlement can satisfy the synthesis trench settlement prediction,and provide a theoretical basis for the analysis of settlement prediction of pipe.
