针对昆明铁路枢纽工程强膨胀岩浅埋富水隧道,采用现场监测和Midas-GTS有限元模拟的手段,提出强膨胀富水隧道围岩控制关键技术,构建强膨胀岩富水隧道稳定动态反馈评价体系.将三台阶加中立柱法(3S1C)与台阶法、交叉中隔墙法(CRD)进行对比,优化施工方法,达到确保工程安全、加快施工进度、节约项目成本的目的.在同等地质灾害条件下可以指导施工,有效减少施工中带来的安全事故.
Aiming at the shallowly-buried and water-saturated tunnel with strong expansive rock in Kunming railway hub project, the key technologies of surrounding rock control in strong-swelling and water-rich tunnel are proposed by means of on-site monitoring and Midas-GTS finite element simulation to build a stable dynamic feedback evaluation system for water-rich tunnel with strong swelling rock. By comparing the three steps plus neutral column method (3S1C) with the step method and the cross centering wall method (CRD), the construction method is optimized so as to ensure the safety of the project, speed up the construction schedule and save the project cost. Under the condition of the same geological disasters Can guide the construction, effectively reduce the safety accidents caused by construction.
