稀疏排桩与锚杆联合技术在深基坑支护中的应用

Application of Sparsely Spaced Soldier Pile and Ground Anchor in Deep Excavation Support

随着城市的发展,深基坑工程越来越多,如何进行深基坑支护设计,既能减少周围建筑与环境影响,又能节约成本,是山区城市建设中常遇到的问题。以三明某建筑工程地下车库基坑开挖为例,合理的采用稀疏冠梁排桩与锚杆联合技术支护方式,在复杂的周围环境和狭窄的施工作业面下,确保了周边建筑和基坑安全,同时也节约空间和成本,今后在类似深基坑支护工程中具有借鉴意义。

With the developments of the urban projects,revitalization of the old cities and the popularity of skyscrapers,deep excavation supporting design methods become increasing diversified.Selection of a deep excavation supporting method that can minimize the impact on the adjacent environment and is also cost effective,is frequently encountered in the urban construction in the mountain area.This paper presents a case history of the deep excavation supporting design for an underground parking garage.The sparsely spaced soldier pile and ground anchor were used as the excavation supporting structure under the confined spacing and complicated adjacent environment.The application of the combined methods safeguards the excavation construction,minimizes the impact the nearby buildings and saves the cost and construction schedule.
