In the same time , the author compiles one set of software with friendly surface and embeds the function that can trains compaction by using neural network into the software system 同时编制了界面友好的应用软件,并创造性的把对压实度的神经网络训练功能嵌入到软件系统当中。
Based on domestic and foreign research achievements about the compaction measurement , this paper puts forward the viewpoint that to use in - vehicle compaction meter to measure the soil compaction 本文在借鉴国内外对压实度检测方法研究成果的基础上,提出应用随车压实度检测方法来测量控制土壤的压实程度。
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。
According to the basic equation for water flow in subgrade soil , based on the basic soil properties of compacted loess , the redistribution of soil moisture and the soil water - migrate parameters are studied 摘要基于黄土路基压实后土体的基本性质,根据路基土中水分运动的基本方程,通过室内一维土柱入渗试验,得到不同压实度的黄土湿润锋湿度与平均湿度、水分入渗速率的关系曲线。
( 5 ) gpr tests were tried out in actual highway , then the practicability , rationality and accuracy are discussed in the bases of analyzing actual data . the results show that using gpr to survey pavement moisture and voids is an effective method ( 5 )用探地雷达在实际路面采集数据对路面含水量、空隙率和压实度进行检测,通过对数据的分析处理探讨探地雷达检测路面质量的实用性、科学性和精确性。
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。
Using mounts of r - surface wave data sampled by practical engineering of dynamic compaction . the compaction degree and uniformity of dynamic foundation are systematically discussed in the thesis . the collected data of in situ testing , combined with r - wave velocity parameter , was used to develop the way to estimate the bearing capacity by multi - parameter and neural network 通过实际强夯地基处理工程的大量瑞雷面波资料的采集、资料的处理,以及成果的分析,对强夯地基的压实度、均匀性进行研究和系统性探讨;收集了原位测试数据,并结合瑞雷面波波速参数,开展多参数拟合和神经网络预测地基承载力的研究。
In the aspect of compaction meter , although many factories can manufacture many kinds of vibratory rollers that can meet the needs of industry , the compaction meter is fallen behind and the equipments produced cannot adapt to the needs of quick development of civil road construction 在密实度检测仪方面,虽然目前国内生产厂家已能生产出多种型号的振动压路机满足工程施工的需要,但与其配套的压实度检测仪尚显落后,且已研制的设备不能适应目前国内公路建设迅速发展的需要。
So far as the mixing material for building the earth - rock fill dam with clay core for shiquanhe hydropower station is concerned , the effect from the variation of the sand content for the filter material on the maximum dry density and the relevant parameters are to be determined within the variation area of the mixing mass ratio of ( 46 ~ 54 ) : ( 54 ~ 46 ) through this experiment , due to the max , dry density is largely influenced by the mixing ratio of both the lifter material and the clay and the sand content of the filter material , so as to determine the actual filling compactness of the mixing material of the core 摘要由于狮泉河水电站粘土心墙土石坝掺合料的最大干密度受反滤料与粘土料的掺合比例、反滤料含砂率的影响较大,因此拟通过本试验确定掺合质量比在( 46 ~ 54 ) : ( 54 ~ 46 )范围变化时,反滤料含砂量变化对最大干密度的影响程度及相关参数,从而确定心墙掺合料填筑的实际压实度。
After contrasting and analyzing the main design parameters " test methods of laboratory and field outside , it sets up the correlativities between the field bearing plate modulus and other parameters such as design dynamic modulus , benkleman bean static deflection , field cbr value , consistency and density . by means of laboratory experiment , it assays the influence of the consistency on laboratory bearing plate modulus and laboratory cbr values , and establishes the relationships between laboratory and field values . combined with the project , a more logical sub - grade quality test standard is put forward 通过对路基现场检测不同方法的对比分析,建立了设计动模量、贝克曼梁静弯沉、现场cbr 、稠度和压实度与现场承载板模量的关系;通过室内试验,分析了稠度对室内承载板、室内cbr的影响,并建立了室内外模量间的关系;在此基础上,结合工程实际,对不同检测方法进行了评价,提出了较为合理的路基施工质量检测标准。
