Environment Geochemistry Problems Pertaining to Tunnel Engineering

摘要

In this paper, the environment geochemistry problems pertaining to tunnel engineering are discussed in the point of view of the sustainable development principle. The environment geochemistry problems, which do harm to human health and environment, occur mainly during the processes of tunneling and running. According to their geo-geochemical features of the problems, they can be divided into four types, i. e. ① erosive underground water, ②noxious gas, ③pollution of poisonous materials and ④ radiation of radioactive substance. The geo-geochemistry natures of those four types of environment problems are described in the point of view of their occurrences. Those features may help us to avoid or control some environment geochemistry problems during both designing and tunneling processes.
