湖北省三峡库区滑坡勘查评价几个问题的商榷

SOME QUESTIONS IN THE ASSESSMENT AND INVESTIGATION OF THE LANDSLIDES IN THE THREE GORGES RESERVOIR

三峡库区地质条件复杂,在滑坡勘查评价中,判定滑带与软弱夹层、确定滑带土抗剪强度参数、地下水位在稳定性计算中的影响作用,是目前三峡库区滑坡稳定性勘查评价中常见的问题。本文提出了解决这些问题的方法建议。

In the Three Gorges Reservoir area, the common questions in the assessment and investigation of the landslide stability are the delineation of the sliding zone and weak interbeds, clarification of the shearing strength coefficience of the sliding soil, and the underground water level and its imputs on landslide stability. All these questions are discussed in the paper.
