舟坝水电站库区某移民新场址的稳定性评价

A NEW IMMIGRATION FIELD SITE'S STABILITY APPRAISAL OF A STOREHOUSE DISTRICT IN ZHOUBA HYDROELECTRIC POWER STATION

受拟建马边河舟坝水库蓄水影响,库区部分老场镇将被淹没,前期资料表明,目前规划的某新场址位于一古滑坡体上,因此该滑坡的稳定性对拟建场址移民居住的适宜性有决定性的作用。通过阐述该滑坡的地质条件及成因机制、变形破坏特征,对滑坡进行了定性分析和定量综合评价。结果表明,该古滑坡体在现状及蓄水后均处于整体稳定状态,但局部受场址的开发性影响可能存在局部失稳,建议采取一定防护措施,以满足移民新场址要求。

Influenced by the storing water of Zhouba reservoir in Mabian river, some old fields town of the storehouse districts will be submerged, and the preliminary material indicated that a new field site is located on an ancient landslide body at present. Therefore, this landslide＇s stability to the new field site which constructing for immigrant to live to have the decisive function. This article elaborated the landslide＇s geological condition, the origin mechanism, the distortion destruction characteristic, qualitative analysis and quantitative evaluation, and the result indicated that the ancient landslide body is at the whole steady state at present and after storing water situation, but the partial would possibly lose the steadily by the field site＇s development influence. It is suggested to carry on certain protective measure,could be satisfied with the new field site＇s request of immigrants.
