北京市昌平区南新村地裂缝成因及防治措施浅析

Genesis of Geofractures in Nanxin Village of Beijing and the Control Measures

本文在查阅大量基础地质资料和前人工作成果的基础上,通过实地调查、地球物理探测,认为构造活动.土体构造解理和第四系基底差异、地下水位超采是造成北京市昌平区南新村地裂缝的主要因素,提出了避让、工程措施和限制地下水超采等防治措施。

This paper presents a study of the geofractures in Nanxin Village, Changping District, Beijing, which is based on consultation of voluminous basic geological data and previous work results, and by carrying out on-site inspection and geophysical survey of the area. It is considered that the main factors causing the geofractures include the tectonic activity, soil structure, difference in the Quaternary basement and excessive groundwater mining. Accordingly, some prevention and control measures are suggested, including evasion, engineering measures and restriction on groundwater mining.
