深基坑对既有超限高边坡支挡结构影响及对策研究

Countermeasures and influences of deep excavations on retaining structures of existing high slopes

通过某工程实例,采用ANSYS程序建立二维模型,结合边坡工程设计与施工的总结,就深基坑对既有支挡结构的影响及对策进行研究,主要包括深基坑开挖未支护、支护工况下支挡结构的应力、应变分布规律,采取相应支护结构进行支挡等对策,有重要的理论和实际意义。

Based on an engineering example a 2-dimensional model is established by use of ANSYS. The countermeasures and influences of deep excavations on retaining structures of the existing high slopes are studied combining with experience of design and construction of slope engineering. This work mainly includes the distribution laws of stress and strain on the tunnel of high slopes with and without retaining structures as well as the countermeasures of retaining structures. It has important theoretical and practical significances.
