摘要
文中以厦门第二西通道石鼓山段公路隧道基坑工程为例,采用数值分析和现场测试等方法,研究开挖卸荷作用影响下的公路隧道基坑变形特性,探讨围护结构嵌固深度、超载大小及位置等因素的影响规律,并提出控制围护结构侧移、防渗等措施降低基坑施工对周边环境的影响。
Based on the foundation pit project of highway tunnel in Shigushan section of Xiamen Second West Channel,numerical analysis and field test were used to study the deformation characteristics of highway tunnel foundation pit under the influence of excavation and unloading.The influence law of the embedded depth,overload size and position of the envelope structure was discussed,and measures such as controlling the lateral shift and seepage prevention of the envelope structure were proposed to reduce the impact of foundation pit construction on the surrounding environment.
