扩大分条数目的瑞典分条法对土坡稳定性的评价

On the Slope Stability Evaluation by Expanding the Number of Points of the Swedish Slice Method

分析黏性土边坡瑞典分条法(10分法)稳定性算法和扩大分条数目的瑞典分条法稳定系数K。分析认为:黏性土土坡的稳定性在一般工程地质评价中,理论计算方法多选用费伦纽斯和泰勒提出的瑞典分条法,分条数目多选用10分法计算;分条数目在一定程度上影响黏性土土坡的稳定性K值,在一定的区间范围内,随着分条数目的增加,黏性土坡的稳定性也在相应增加。

This paper analyzes the stability of the Swedish slice method for the cohesive soil slope and stability factor K of Sweden slice method expanding the number of points.The analysis shows that Swedish slice method proposed by Fellenius and Taylor method was always used as theoretical calculation method,and the number of points selected 10 in the cohesive soil slope in geological evaluation of general engineering.The number of points affect the the value of cohesive soil slope stability K in a certain extent.In some range,with the increase of number of points stability of clay soil slopes is also a corresponding increase in.
