摘要
嵌岩桩因单桩承载力高在工程上得到广泛应用.迄今为止,嵌岩桩的荷载传递机理尚不完全清楚,单桩沉降的影响因素又十分复杂.以ABAQUS为平台,对嵌岩桩的荷载沉降特性进行了全面的有限元分析,探讨了嵌岩桩受竖向荷载作用下影响单桩承载力及沉降的各种因素.分析结果表明,嵌岩深度、桩身弹性模量、嵌入岩石弹性模量、沉渣厚度是影响单桩承载力及沉降的主要因素.
Rock-socketed piles are used frequently due to their superiority of high bearing capacity. Till now, their load transfer mechanism is not distinct; and the factors influencing the settlement of single rock-socketed pile is very complex. This paper presents a finite element method to analyze the load-settlement characters of rock-socketed piles based on ABAQUS; the factors, influencing single pile bearing capacity and settlement of rock-socketed pile under vertical load are then discussed herein. The analytical results indicate that the rock-socketed length, the elastic modulus of pile shaft and the elastic modulus of socketed rock are the important factors influencing the capacity and the settlement of single rock-socketed pile.
