填方较之挖方有更大的不确定性,而由于泥灰岩独特的工程特性,泥灰岩地基的填方将更为复杂,特别是斜坡填方工程,因此应得到足够的重视。较为系统地论述了阿尔及利亚东西高速公路泥灰岩斜坡填方所涉及的问题,包括填方材料的选择、稳定性计算的假定、稳定性计算的目标、抗剪强度参数取值、采取的技术方案以及填方病害的分析整治等,可供泥灰岩地区工程项目参考借鉴。
There is more uncertainty about the fill than the cut and due to the unique engineering characteristics of marl, the filling of marl ground will be more complicated, especially for slope fill works and therefore deserves sufficient attention. This paper systematically discusses the problems involved in the slope filling of marl limestone on the east-west highway in Algeria, including the choice of filling materials, the assumption of stability calculation, the target of stability calculation, the value of shear strength parameters and the technical solution adopted As well as the analysis and rectification of filling disease, which can be used as a reference for engineering projects of marl.
