吕家坪公路隧道地质勘察与施工监控

The Geological Reconnaissance and Construction Monitoring-controlling of Lu Jiaping Highway Tunnel

长江三峡工程是举世瞩目的特大水利工程,库区交通复建工程与环境地质的矛盾极为突出,文章以三峡库区交通复建工程—秭归县吕家坪公路隧道为例,介绍了该隧道工程地质勘察、选线、施工中对长江三峡重大危岩体—链子崖危岩体的稳定性和安全进行重点关注,开展监测监控,确保危岩稳定的前提下顺利贯通隧道。

The project of Yangtze River Three Gorges is the supergiant hydraulic project which attracts worldwide attention. The contradiction between the recovering construction project of transportation and the environment geology in the reservoir area is extremely prominent. This article takes the recovering construction project of transportation in Throe Gorges Reservoir Area——the Lu Jiaping highway tunnel of Zigui County as an example, and introduces the focus on the stability and security of the momentous hazardous rocks-the Lianziya hazardous rocks in Yangtze River Three Gorges in the geological reconnaissance, the lines selection, and the construction of the tunnel, and conducts the monitoring - forecasting and monitoring - controlling to guarantee the run through the tunnel smoothly with the promise that the hazardous rocks are stable.
