建筑垃圾制再生骨料CFG桩影响因素的模拟研究

The simulation study on the influencing factors of recycled aggregate CFG pile making use of construction waste

论述了建筑垃圾的来源及其基本特性,认为建筑垃圾经过处理后,可以成为有用的建筑材料。通过有限差分软件对建筑垃圾制再生骨料CFG桩的影响因素进行分析,探索出了桩长、褥垫层、桩土应力比与桩轴力间的关系;同时也考虑了桩顶上加褥垫层和基础的因素,使之更切合工程实际。通过系列数值分析,对建筑垃圾制再生骨料CFG桩的理论和实践的发展有一定的参考价值,为常规CFG桩设计与施工提供重要参考。

This article discusses the sources of construction waste and its basic characteristics,and puts forward the idea that the construction waste can be useful building material after treatment. The influencing factors of CFG pile making use of construction waste are simulated by the finite difference software, and the relations between pile length,cushion,pile-soil stress ratio and axial force of pile are found. Factors of adding cushion and foundation above the pile top are also considered to make it more practical. The conclusions obtained through series of numerical analysis have certain reference value for the development of theory and practice of CFG pile making use of construction waste,providing important reference to the design and construction of CFG pile.
