摘要
引水隧洞是水电工程的重要组成部分,大多布置在深山峡谷,属于典型的地下工程,且其具有埋深大、洞线长、断面大、地质条件复杂等特点,施工过程中会面对诸多不确定因素。为了随时应对突发问题,需要对不良地质洞段的具体情况进行分析、制定出相应的解决措施,当不良地质洞段出现问题后能够高效、快速地进行处理以确保施工人员和设备的安全。阐述了对长隧洞、大断面不良地质洞段施工措施进行的研究。
The headrace tunnel,mostly arranged in deep mountain canyons,is an important component of hydropower projects,and it is a typical underground engineering.It has the characteristics of large burial depth,long tunnel line,large section,and complex geological conditions.During the construction process,many uncertain factors will be faced.In order to deal with the unexpected problems at any time,it is necessary to analyze the conditions of the unfavorable geological cave section and to formulate corresponding measures.When problems occur in the unfavorable geological section,they can be efficiently and quickly handled to ensure the safety of construction personnel and equipment.This paper introduces the research on construction measures for the unfavorable geological cave section of long tunnel with large section.
