Abstract Incompressible dipping substrata are commonly encountered in engineering practice. Compared to horizontal underlying strata, the inclined underlying stratum increase the risk of collapse of embankments reinforced with columns because it weakens the restraint of the column base. The objective of this study is to investigate the effectiveness of geosynthetics on improving the embankment stability when the underlying stratum is inclined. The influence of geosynthetic tensile stiffness on the ultimate surcharge and failure mechanism is studied. A deep-seated failure with column tilting occurs when the geosynthetic tensile stiffness is low, whereas a lateral sliding occurs when the geosynthetic tensile stiffness is high. To illustrate the contribution of geosynthetics, the distribution of the lateral pressures acting on the columns is analyzed.

土工合成材料加筋对斜埋地层刚性柱路堤稳定性的影响

摘要 工程实践中经常会遇到不可压缩的浸渍基材。与水平下伏地层相比，倾斜的下伏地层削弱了柱基的约束力，增加了柱加固路堤的坍塌风险。本研究的目的是研究土工合成材料在下伏地层倾斜时提高路堤稳定性的有效性。研究了土工合成材料抗拉刚度对极限超载和破坏机制的影响。当土工合成材料的抗拉刚度低时，会发生柱倾斜的深层破坏，而当土工合成材料的抗拉刚度高时，会发生侧向滑动。为了说明土工合成材料的贡献，分析了作用在柱上的侧向压力的分布。
