-
摘要: 西宁市某深基坑工程地质条件及周边环境复杂。根据深基坑工程的基本理论及相关规范,对该基坑的围护方案进行论证,确定采用锚拉排桩围护结构,完成了围护结构的布置、结构计算;并对基坑的抗倾覆、抗隆起稳定性进行了验算。实践证明:该设计方案安全可靠,并对同类工程有一定的参考价值。Abstract: The engineering geological conditions and environment of a deep excavation in Xining is very complicated.Based on the elementary theory and interrelated codes of deep excavations,a demonstration is carried out for the enclosure scheme,the anchor bar and piles in row are used for the enclosure,the arrangement of the enclosure and calculation are also completed.The stability of withstanding tipping and uplift resistance are checked.Practice has shown the design scheme is safe and reliable,which provides a reference for similar projects.
