北京市顺义平原区地质环境的主要特征及地质灾害现状
|
摘要
文章对顺义区地质环境的主要特征及地质灾害现状进行了初步研究。该区地质环境比较脆弱,断裂活动性强,地震活动频度高,松散易液化的细粉砂土及不规则分布的软土分布面积较广,地面及地基工程地质条件较差、水资源不足,容易发生地震、地裂缝、砂土液化、地面沉降、水环境污染及地基失稳等地质灾害。建议进行专门的综合性地质环境及地质灾害调查研究工作,为顺义区总体发展规划、保护生态环境以及减少地质灾害损失等提供科学依据。
On the basis of the large survey to the land resources and geologic environment in Shunyi county, this paper preliminarily studied the present situation of geologic environment and geologic hazard, regarded the gologic environment of Shunyi county is unfavorable, e. g.strong fault activity, frequent earthquake, wide distribution of Quaternary strata, easily liquefacted loose sandy soil, and bad geologic condition of ground and foundation engineering, insufficient water resources. These can easily cause geologic hazards such as ground deformation, earthquake, ground fissure, land subsidence, water environment pollution and unstable foundation. The paper suggested to make a special comprehensive investigation of geologic environment and geologic hazard in order to provide scientific basis for the general plan of development, for the protection of ecological environment and for the reduction of loss caused by the geologic hazards.
