深圳孤石形成因素与特点分析
|
摘要
孤石在我国分布较广,特别是东南沿海地区。深圳市坐落在我国南海之滨,市区内分布着大量的孤石,而随着人们对孤石地区的占用,孤石灾害越发频繁,已给城市生活生产带来了极大的安全隐患。治理孤石灾害首先要清楚孤石的形成因素,立足深圳市,着重研究深圳市孤石的形成因素与特点,为孤石的治理提供技术支持。
The spheric weathered granite is widely distributed in China,especially in the southeast coastal region. Shenzhen is located on the coast of the South China Sea,there are lots of spheric weathered granite in the urban area,with the occupation of the boulder area,the spheric weathered granite disasters more frequent. Analyzing the factors and characteristics of spherical weathered granite in Shenzhen,and providing technical support for spheric weathered granite management.
