摘　　要：在研究多雨山区资源热力电厂深挖高填工程施工的基础上,开展对高含石量碎石土填料的力学性能试验研究,对不同填料、不同地基处理方式及施工参数的效果进行比较,优选合理的地基处理方式、施工参数,并模拟实际填筑方案,将试验得到的黏聚力、内摩擦角和弹性模量应用到数值计算中,分析填筑过程中的应力变化。研究结果表明:碎石与土比例为7:3且碎石为中风化~微风化的粗粒径碎石土混合料,其力学参数满足60m高填方边坡的设计要求。经五年累计监测,高填方边坡安全稳定,满足工程要求。On the basis of the study of the rainy mountain resources thermal power plant dig high filling engineering construction,the mechanical properties of high stone gravel packing were carried out.The effect of different packing,different foundation treatment methods and construction parameters was compared,optimizing the reasonable foundation treatment mode,construction parameters,and the actual filling scheme was simulated.The test cohesion,internal friction Angle and elastic modulus applied to the numerical calculation,the stress changes in the process of filling were analyzed.The results show that the ratio of gravel to soil is 7:3 and the gravel is a coarse grain diameter gravel soil mixture,and its mechanical parameters meet the design requirements of 60m high fill slope.After five years of cumulative monitoring,the high fill slope is safe and stable,and meets the requirements of the project.
