摘要:
以施工现场大量监测数据及类似工程经验为基础,从土力学基本原理出发,结合岩土工程分析软件FLAC3D的三维有限差分法数值模拟计算结果,就软土地区深基坑施工过程对既有地铁盾构隧道结构的影响原理及规律做了研究。提出基坑施工过程坑外土体位移的聚合引力场域概念并得出主要结论:软土地区深基坑施工对周围既有结构的影响范围与软土地层本身的物理参数如内摩擦角、黏聚力、泊松比等密切相关。地层流变性越强,灵敏度越高,其影响范围就越大,所有处于聚合引力场域中的既有结构都会受到影响甚至被破坏; 聚合引力的大小及聚合面会随着基坑开挖面的加深而逐渐变大并向下移动,处于动态发展的过程中。
Abstract:
In order to study the construction of deep foundation pit in soft soil area of existing subway shield tunnel structure principle and the influence of the law,based on a large number of monitoring data of construction site and engineering experience as the foundation,this paper uses the geotechnical engineering analysis software FLAC3D and according to the results for the first time put for polymerization gravitational field domain concepts,and draws some important conclusions:for deep foundation pit construction in soft soil area on the surrounding,the influence of both the structure and its formation is the physical parameters such as internal friction angle,cohesive force,poisons'ratio closely related.Formation rheological property,the higher the sensitivity,the greater the impact scope.All in the polymerization of gravitational field domain existing structures are affected or even damaged.Polymerization gravity and the size of the polymer surface will gradually become larger with the excavation of the deepening and move down,it is a dynamic process.
