摘要
以石家庄正定新区安济路综合管廊工程暗挖段为背景,根据其周边环境的独特性,拟采取的2种设计方案,对比分析初期支护断面形式、受力体系转化、机械使用条件、安全、工期、成本等多个方面,选出最佳方案设计,设计关键技术措施,并在项目中成功应用,对今后类似砂层地区管廊暗挖隧道横穿构筑物的设计有重要的借鉴意义。
Taking the underground excavation section of Anji Road Comprehensive Pipe Gallery Project in Zhengding New District of Shijiazhuang as the background, according to the uniqueness of its surrounding environment, the two design schemes proposed to be adopted are compared and analyzed in terms of initial support section type, stress system transformation, mechanical use conditions, safety, construction period, cost, etc., to select the best scheme design, design key technical measures, and successfully apply them in the project. It has an important reference significance for the design of tunnel crossing structures in similar sand layer areas in the future.
