摘要
基于青岛地铁9号线海西村站深基坑现场工况及监测数据,开展有限元仿真计算,分析破碎玄武岩地层中深基坑的开挖变形特性,并探索破碎带强度和刚度参数折减、破碎带大小及空间位置对基坑开挖变形的影响效应。总结了破碎带的处理措施,该研究成果有助于指导破碎玄武岩地层中深基坑的设计和施工。
Utilizing field conditions and monitoring data from the deep excavation at Haixi Village Station on Qingdao Metro Line 9,finite element simulations were performed to examine the deformation behavior of deep excavations within frac-tured basaltic strata.The investigation focused on the impact of reduced strength and stiffness parameters within the fractured zone,as well as the influence of the dimensions and spatial distribution of the fracture zone on excavation deformation.Treatment measures for the fractured zone were summarized,and the findings of this study help guide the design and construction of deep excavations in fractured basalt strata.
