花岗岩地区滑坡特征及防治对策——以湖南省平江县花岗岩滑坡为例

文章分析了湖南平江县花岗岩地区滑坡,在地形地貌、地层岩性、地质构造、水文地质条件、滑坡体、滑动面、滑动多期性等方面的典型特征。由于地表水和地下水是花岗岩地区滑坡中的主要影响要素,因此,提出对该类型滑坡应采用排水工程为主,并和其它防治措施相结合的方法进行防治。换言之,排水工程是滑坡防治中单独的一项措施,其效果应在同步进行的滑坡监测中予以验证。在滑坡治理的过程中,滑坡监测始终是滑坡防治的基础,防治的效果也需要监测工作来检验。

Characteristics and Control of Landslide in Granite Region--Taking the Granite Landslide in Pingjian of Hunan as an Example

The representative characteristics of Landslides in granite region of Pingjian county of Hunan, including characteristics of landform, strata and lithology gedogical structure, hydrogeology, landslide body, sliding surface and sliding multistage, etc, are introduced. Because surface water and groundwater is the major incluence factor of landslide in granite region, drainage engineering is put forth as the main measure in landslide control, with the other control engineerings being the accessorial measures. or alternatively, drainage engineering is the sole measure in landslide control, and landslide monitoring should be carried out synchronously to verify its effect. Landslide monitoring is the basis of laqndslide control ifrst midst and last, and its effect need to be veriifed by landslide monitoring.
