By the large quantity of indoor and field soil mechanics test , this paper investigated physics and mechanics property of xigeda stratum and xigeda compounding filling , profoundly and systematically studied on shearing strength , cbr ( including indoor cbr and field cbr ) and intensity feature of xigeda compounding filling . the new achievement and cognition as follows : ( 1 ) cbr value is decided by moisture content and mudstone content of xigeda compounding filling . the filling material can satisfy minimum intensity standard of express highway when mudstone content is less than some fixed value , ( 2 ) this paper established field cbr standard value which can synthetically evaluate the filling material nature and field compaction degree . ( 3 ) the optimal compacting mean of xigeda compounding filling is hard oscillation first and weak oscillation later , not traditional way which is weak oscillation first and hard oscillation later . ( 4 ) this paper put forward the conception of optimum moisture content in construction different from optimum moisture content of indoor impaction 本文以昔格达填料强度特征为研究对象，通过大量的室内及现场试验，从昔格达地层岩组的物理力学性质、昔格达填料的物理性质入手，对昔格达填料的抗剪强度、室内承载比及现场承载比特征进行了较系统地研究，获得了如下认识及进展：昔格达混合填料承载比值受填料含水量及其中泥岩含量的影响，当泥岩含量小于一定值时，昔格达混合填料具有较高的承载比值，能够满足高速公路对填料的最低强度要求；建立了综合评判昔格达填料性能及现场压实效果的现场承载比( cbr )标准；对于昔格达填料而言，最佳的碾压方式为先强振后弱振而不是传统的先弱振后强振；提出了与室内击实最优含水量相区别的施工最佳含水量的概念。
When dim pile is applied in work of a freeway project , it is conducted as a study issue , because both the theory about it is not very clear now and also the quality control is hard to demonstrate , in addition , there is a big difference among soft soils in different areas on the distribution , the ingredient of minerals and the physical and mechanical properties 由于这一方法的理论还太完善，施工质量控质也有一定难度，加上不同地区软土的土层分布，软土的矿物成分、物理力学性质等差异性极大，所以每项高速公路工程在采用粉喷桩处理软基时，都将其列为一项研究课题。
