摘要
以深圳勘察项目为例,分析地铁隧道穿越花岗岩残积土形成上软下硬土层的机理和工程物理力学特性,详细介绍盾构法在不同地质情况下,掘进参数和渣土改良的关键技术,并为类似工程提供参考。
Taking a reconnaissance project in Shenzhen for example, the mechanism and physical and mechanical characteristics of Upper-soft Lower-hard ground in granite residual soils are analyzed in this paper. The key technique measure of construction parameters of shield method and muck conditioning tech-nology are introduced in detailed and can provide some references for similar engineering.
