【摘要】 随着国家基础设施向绿色低碳方向转型，高地应力环境下的地下工程数量日益增多，传统施工方法面临高能耗、高排放的挑战。尤其在软岩隧道施工中，大变形问题不仅威胁工程安全，还可能因支护冗余造成建材浪费和生态扰动。因此，开展高地应力软岩地层围岩稳定性与低碳施工协同控制研究，对推动隧道工程节能降耗与环境保护具有重要意义。本文依托都四山地轨道交通工程观音坪隧道，通过现场试验监测手段，分析高地应力条件下软岩地层隧道施工的围岩稳定性。试验结果显示，开挖过程中最危险的位置为隧道拱部，各结构受力均属于可控状态。更多还原

【Abstract】 With the transformation of national infrastructure to a green and low-carbon direction, the number of underground projects in high geostress environment is increasing, and traditional construction methods are facing the challenges of high energy consumption and high emissions. Especially in the construction of soft rock tunnels, the problem of large deformation not only threatens the safety of the project, but also may cause waste of building materials and ecological disturbance due to redundant support. Therefore, it is of great significance to carry out the research on the stability of surrounding rock and low-carbon construction of high geostress soft rock strata to promote energy saving, consumption reduction and environmental protection of tunnel engineering. In this paper, relying on the Guanyinping Tunnel of the Dusi Mountain Rail Transit Project, the stability of the surrounding rock and the green construction control strategy of the tunnel construction in soft rock strata under high geostress conditions are analyzed through field test monitoring methods. The test results show that the most dangerous position in the excavation process is the tunnel arch, and the force of each structure is controllable.更多还原
