高速公路路线选择与地质灾害关系的研究

The Study on the Relationship Betwenn the Route Choose of Expressway and Geological Dizaster

本文通过一条高速公路路线勘选的工程实例,研究了高速公路路线选择与地质灾害间的关系。认为,路线选择前,路线走廊及周围地区现时及未来地质灾害的勘查至关重要。这些灾害包括水库塌岸、洪水、断层和断裂带、滑坡、泥石流、崩塌等,路线选择应尽量避开这些灾害地区。对不能避开的地质灾害,应视其特征用不同方法治理,同时应兼顾工程造价、环保及行车舒适等情况。

By means of a case of expressway route survey and choice, the relationship between the geological disaster and the route choice of expressway is studied. It is thought that, it is very important to survey the geological disaster to the passageway and around before the route choice. The geological disaster consists of the reservoir side-slope collapse, flood, faults, fault zone, landslide mud-rock flow and so on. The principle of the route choice is keeping away these disasters. If some geological disasters we can＇t be avoided, we must take some measures to control them according to the different disaster condition. At the same time we must give the consideration to the engineering cost, environment protection and - able driving.
