水工隧洞施工的环境保护主要有两个方面:一是保证隧洞工程周围环境现状;二是如何保证洞内作业环境能控制在规定的标准之下。这是当前发展和改善施工技术的一个重要出发点。1水工隧洞工程周围环境现状调查的内容水工隧洞工程周围环境调查要选取被认为因隧道的修建
The construction of hydraulic tunnel environmental protection mainly in two aspects: First, to ensure the status of the surrounding environment of the tunnel project; Second, how to ensure that the operating environment within the cave can be controlled under the provisions of the standard. This is an important starting point for the current development and improvement of construction technology. 1 Hydraulic Tunnel Surroundings Surroundings Survey Investigation Content Surrounding Surveys of Hydraulic Tunnel Surveys To be selected is considered to be due to the construction of the tunnel
