field compaction meaning in Chinese
野外压实
Examples
- However , at present the heavy rammer method is still used to determine the standard of compactness and molding specimen by still compressive force in laboratory testing . which leads to the inconsistency of compaction mode between field compaction and laboratory compaction
但作为现场施工指导的室内试验，依然采用击实法确定压实度标准，静力压实法成型试件，导致室内试验的压实方式和现场压实状况不一致。 - 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。 - Directed against the lack of laboratory equipment that can simulate field vibratory compaction , a vibratory compaction apparatus that can simulate the mechanical structure of vibratory roll , and can regulate vibratory parameters , is developed through the analysis of influence factors of field compaction effect for vibratory roll , such as structure parameters and vibration parameters
本课题针对室内缺少能够模拟现场振动压实状况的振动压实设备的现状，在深入分析影响振动压路机现场压实效果的因素如振动参数、结构参数等的基础上，自行研制加工了在结构上可以模拟振动压路机的机械结构且振动参数都可调的振动压实成型设备。
