浅析花岗岩流失区重力侵蚀对民房的危害及其防治

Preliminary Analysis about Harm of Lifehouses Caused by Gravity Corrosion in Granite Draining off Region

我省重力侵蚀主要发生在花岗岩流失区.这里的民房常建在陡坎下,突遇罕见的大暴雨时,诱发大规模崩塌,造成房倒人亡的灾害.文中以万安、遂川两次灾害的调查为基础,分析其发生的原因,提出了工程与生物相结合的防治措施.

The gravity corrosion generally takes place in granite region in our pr- ovince.In these regions,lifehouses have been built below steep gradient in ge- neral.At the terrible storm time,large landfull following houses falldown and vital harm could happen.In this article,the author has proposed some projective and biological measures,based on the investigation and the cause analysis for two accidents in Wanan and Shuicuan county.
