福州轻轨交通环境地质问题分析
|
摘要
以福州轻轨交通1号线为例,通过对拟建线路所处地质环境背景的实地调查,结合铁路工程技术标准、规范和要求,选取水文工程地质条件、构造条件、地形地貌条件、气候条件、工程构建物及其施工条件等为主要评价要素,初步预测分析和评价了工程项目在建设中及建成后可能引发或工程建设本身可能遭受的各种环境地质问题,主要有基坑突水、压覆温泉、隧道围岩失稳、地面沉降、基坑边坡失稳、断裂活动破坏、温泉超采危害、浅层气包裹体危害、桥梁地基失稳及地震砂土液化等,以为福州地区城市交通建设提供依据。
Taking No.1 Line of Fuzhou light rail as the example,this paper predicts,analyzes and assesses the various geological hazards that may by caused in and after the project construction or may be encountered by the project construction by investigating geological environment background along the planned light rail route,considering the engineering and technological standards,regulations and requirements of railway construction and taking many factors as the assessment elements,such as the conditions of geology and hydrology,structural geology,topography and landform,climate and project.The major geological hazards may occur as follows: the destruction of rupture activity,the excessive exploitation of hot springs,the instability of bridge foundation,the harm of shallow gas,the liquation of earthquake sandy soil and so on.This study can provide the reference for the public transportation construction of Fuzhou City.
