| 摘 要： | 在穿越隔水板岩和透水碳酸盐岩间接触带时,隧道施工将遇到一系列工程地质问题,这对地质条件适应性较传统钻爆法差的TBM掘进来说尤为突出。结合TBM施工的云南上公山隧道工程,通过对该接触带工程地质条件评价和问题分析,讨论了该洞段的泥石流、库水位下降、泉水断流等一系列环境工程地质问题的发生机理。

| Abstract: | When the Tunneling Boring Machine (TBM) passing through the contact zones between slate and carbonate, engineering geological problems emerged. These problems were more serious than those encountered when traditional drill-blasting method was used due to the lower adaptability to complicated geological conditions in TBM. Taking the Shanggongshan tunnel project as a case example, this paper presents the engineering geological conditions of the contact zone, trying to disclose the mechanism for a set of environment engineering geological problems, e. g. debris flow, water loss from overlaying reservoir, and disappearance of springs. As a result, it was found that the contact zone was controlled by faults with fractured rocks favorable to groundwater storage and flow in the drainage area. |
