摘要
2020年11月,滇中引水工程香炉山隧洞4号施工支洞发生突泥涌地质灾害,在治理过程中,引用“方钢混凝土拱架”进行支护施工,经不断试验优化总结,摸索出一套较为适用4号洞大倾角高埋深极富水条件下抑制软岩大变形的方钢混凝土支护体系。
In November 2020, mud gushing geological disaster occurred in No. 4 construction branch of Xianglushan Tunnel of Yunnan Water Diversion Project. "Square steel concrete arch" is used for support construction during treatment. Through continuous test and optimization summary, a set of square steel concrete support system suitable for restraining large deformation of soft rock in No. 4 tunnel with large inclination, high buried depth and very rich water is found out.
