摘要
随着经济建设的发展,人类工程活动逐渐向地质环境复杂的山区扩展。受强烈构造作用影响,导致山区地质灾害频发,严重制约着交通建设和城镇化的进程。以广安市区城市总体规划用地为例,在详细调查的基础上,对区内地质灾害发育特点进行了分析,并结合规划用地需求,采用定性和半定量相结合的方法,将区内地质灾害进行综合分区评价:共划分为高、中、低易发3个大区,分别包含了3、7、15个亚区。同时结合规划用地类型,对场地适宜性做出了评价,从而指导人类工程活动,减少地质灾害的发生,避免造成不必要的人员伤亡和财产损失。
With the development of economic construction,human engineering activities gradually extend to the mountain,where contains complex geological environment.Affected by the strong tectonic effects,leading to frequent geological disasters,the expansion of transportation construction and urbanization have been seriously restricted.In this paper,take the example of Guang'an urban overall plan areas,on the basis of a detailed investigation,the characteristics to geological disasters in this area has been analyzed.And with the combination of requirements to land use planning.The comprehensive assessment to the geological disasters degree of geological disasters in this area has been made by taking the method of qualitative and semiquantitative.The area has been divided into three major areas,such as:high,medium and low-prone area,which contain 3,7,15 sub-regions respectively.In addition,with the combination of the type of overall land use plan,the assessment to land suitability has been made to guide human activity,reduce the occurrence of geological disasters,and to avoid unnecessary casualties and property losses.
