摘要
对于软土地基斜坡堤,排水固结、反压平台和加筋层等措施已成为解决整体稳定问题的有效方法。平湖九龙山西沙湾景观配套二期工程的海堤位于软土地基上,堤身高度大,且堤前存在1∶3.5的陡坡,不具备采用反压平台的条件,而完全采用排水固结和加筋层措施,不能经济地解决整体稳定性问题。在堤前增设抗滑桩,有效而经济地解决了整体稳定性问题。
In the design of sloping dike on silt foundation,drain consolidation,overburden layer and geobelt-reinforced cushion are effective solutions to solve the stability problem.The sloping dike in Pinghu Jiulong Mountain complement land-scape second-stage construction locates on silt foundation,with high elevation and steep slope of1:3.5in front of the dike.Overburden layer is not suitable under this condition.The stability of the dike can’t be solved economically through drain consolidation and geobelt-reinforced cushion.So,slope-resistant piles are used to improve the dike stability effectively and economically.
