摘要
根据蔺沟堤防设计参数及地层岩性分布,选取岩性较不利地层断面,利用GEO-SLOPE/W软件构建模型,分别采用瑞典条分法,毕肖普法,简布法,摩根斯坦-普赖斯法计算堤防边坡稳定安全系数,包括正常运用工况及非常运用工况。计算结果表明,地震工况下蔺沟堤防最危险滑动面抗滑稳定不满足规范要求,建议通过工程加固措施进行地基处理以保证堤防安全。
According to Lingou dike design parameters and formation lithology distribution, lithologic less favorable stratigraphic section was selected, GEO-SLOPE / W software was used to build the model, Study of Sweden, Bishop method, briefing method, and Morgenstern - S ＆ P Rice method were respectively used for calculating the safety factor of dike slope stability, including the normal use conditions and abnormal use conditions. The calculation results showed that the anti-skid stability of the most dangerous sliding surface in the Lingou dike did not meet the specification requirements under the seismic conditions, and it is suggested that ground foundation should be treated by engineering reinforcement measures in order to ensure the safety of dike.
