| 中文摘要: |
| 本文以新场河水库滑坡为研究对象，在野外勘查、探明滑坡地质条件和变形特征的基础上，对新场河水库滑坡的成因进行了分析，根据土体压缩特性和固结原理，参照地基变形计算方法，对滑坡稳定性及未来的变形发展趋势进行了评价。研究表明，具备顺层地质条件的库岸斜坡，在库水位升降和降雨联合作用下，即使没有很好的临空滑移条件，斜坡体也会产生蠕滑变形，其变形量的大小与坡体组成物质的压缩性有关。分析研究可为同类水库滑坡防治及安全运行提供借鉴。 |

| In this paper，the landslide of Xinchanghe reservoir is taken as the study object，on the basis of field detailed exploration，measured the geological condition of landslide and deformation feature，the genesis of landslide in Xinchanghe reservoir was analyzedAccording to the soil compression characteristic and consolidation principle，with the computing method of foundation deformation，the stability and future deformation tendency of the landslide were discussedThe results shows:under the influence of water level variation and rainfall，even the air slid condition is not so good，the slope withe bedding geological condition will creep deformed，the deformation value is related to the compressibility of the slope constituent materialsThe study can afford guidance for landslide prevention and safe management of the similar reservoir |
