- Considering that the way to gain standard maximum dry density value of xigeda filling is complex , this paper suggests adopt means combining field cbr test and compactness measuring to control construction quality
鉴于昔格达混合填料标准最大干密度取值的复杂性，建议采用现场承载比与压实度检测相结合的办法进行现场施工质量控制。 - 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。 - Therefore , xigeda filling material is a compounding filling made up of several soft rocks mentioned , which has more complex medium feature than single type filling material . we must certificate whether it satisfy minimum intensity standard of speedway ' s filling if the filling is used as roadbed material of express highway
因此昔格达填料是由上述几类软岩组成的混合填料，与单一类型填料相比具有更为复杂的介质特征，将其用作高速公路路基路堤填料，需要验证其能否满足高速公路对填料的基本要求。 - To control the settlement of roadbed , the degree of compaction regulated by current criterion is not enough , the mechanics parameter of filler compacted - - deformation parameter should be considered and dual control criterion should be put in practice . to get upper deformation parameter of xigeda stratum filler , the percentage of mudstone should be controlled . the thickness of filling layer regulated by current criterion can be increased if the compaction car has proper function
通过此次研究，获得了对路堤变形问题的新的认识，即为了控制路堤的沉降变形，不仅应满足现行规范中规定的压实度标准，还应该引入填料压实后的力学参数? ?变形模量值标准，实行双重控制标准，而对于昔格达地层这种混合填料，为了获得较大的模量值，应该控制填料中泥岩的含量；现行公路路基施工规范中对路堤填筑时分层填筑厚度的规定值，在压实机具功能满足的条件下，可以适当提高。
