摘要:

花岗岩残积土中的孤石给工程施工带来了困难。龙厦铁路象山隧道出口段在施工过程中遇到含大量孤石的花岗岩残积层,除地层不均匀外,该段隧道还具有浅埋、地下水发育等施工不利因素。介绍施工中出现的工程问题,分析这些问题的成因,系统阐述改进的施工方法及措施,对类似工程有一定的借鉴意义。

Abstract:

Boulders in residual granite soil can induce difficulties in tunnel construction. At the exit section of Xiangshan tunnel on LongXia railway, there are plenty of boulders in residual granite soil. Besides the heterogeneous ground, this section of Xiangshan tunnel also has the adverse conditions of shallow cover and ground water. The author introduces the difficulties in the construction and analyzes the causes. Furthermore, he presents the improved construction methods and measures in detail. This paper can provide references for similar projects.

Key words:  residual granite soil, boulder, shallowburied tunnel, soil/water loss
