摘要
以远大购物广场深基坑工程为研究对象,运用岩土组合梁理论分析基坑边坡支护机理,以理论力学、材料力学原理为基础,建立基坑边坡支护结构力学模型,并进行基坑边坡支护结构承载性能的力学计算,结合岩土层力学承载能力的验算,确定深基坑的最佳支护方案及其具体支护参数,最后通过现场应用监测。结果表明:锚杆岩土组合梁方法及其参数支护基坑边坡取得了良好成效,为类似基坑边坡的稳定性控制提供了合理的计算依据。
Taking the deep foundation pit project of Yuanda shopping plaza as the research object,this paper uses the theory of geotechnical composite beam to analyze the supporting mechanism of foundation pit slope,establishes the mechanical model of supporting structure based on theoretical mechanics and material mechanics,and calculates the bearing capacity.On the basis of calculation,the optimum supporting scheme and specific supporting parameters are determined,and the application monitoring is carried out.The results show that the anchor rock-soil composite beam method and its parameters can achieve good results in supporting the slope.This study provides a reasonable calculation basis for the stable control of similar projects.
