石佛寺水库土料碾压试验综合分析

石佛寺水库土料碾压试验综合分析(论文12000字)
摘 要
碾压试验参数是衡量水库各项参数的合格标准，需通过多次反复试验来确定，碾压试验是的一项重要前提工作。所谓碾压试验，就是对一定料质的土料进行代表性取样，按照《实验规程》的相关规定进行试碾压，取得现场数据，然后对取得的数据进行统计分析，得出结论，作为施工的理论指导。为了得到准确的碾压指标，本篇文章针对石佛寺水库坝型为均质土坝，枢纽为Ⅱ等工程，永久性建筑物等级为2级，水库的主坝、右副坝是均质坝以及石佛寺水库的地形地质条件水文等工程具体概况来确定碾压试验的方法，采用EX350反铲挖掘机装15t自卸汽车运输，后退进占法铺料、D85推土机平仓，C25凸块振动碾进退错距法碾压，进而得知碾压试验的具体步骤，先测量放线，然后铺平土料，碾压，最后做质量检验，还要进行含水量调整，要特别注意现场碾压试验需要进行铺土方式、铺土厚度、碾压机械的类型及重量、碾压遍数、填筑含水量等各项参数试验。复合试验应进行土料的颗粒级配、压实土的干密度等试验，颗粒级配是影响标准击实最大干密度和最优含水量的主要原因之一，每项参数都决定着试验结果的成败，所以在试验过程中要严格按照要求控制参数，确保每项参数达到合格要求，进而针对多次的试验结果得到最佳的合格标准，为石佛寺水库提供科学、真实的数据参数，并为提出了相关建议，从而达到合理的技术标准，更进一步得到想要的结果。
本文的研究思路、研究方法和结论可为类似水库工程提供的借鉴和参考，从而为水库的设计、施工提供了更加灵活、多样的解决办法。

Abstract
Rolling test parameters are qualified standard to measure the parameters of the reservoir, determined by repeated tests, an important premise is the compaction test. The compaction test, is of a certain material quality of soil materials for representative sampling test, in accordance with the relevant provisions of the rules of rolling <>, then obtain field data. Statistical analysis of the data obtained the conclusion, as a theoretical guide for construction. In order to obtain accurate rolling index, this article for Shifosi Reservoir dam type for homogeneous earth dam, hub II project, the permanent building for the 2 class, the reservoir dam, right auxiliary dam is of homogeneous dam and concrete Shifosi Reservoir topographic and geological conditions of hydrological engineering method to determine the compaction test, using EX350 backhoe excavator mounted 15t dump truck transportation, paving material back 'method, D85 bulldozer positions, C25 bump The vibration roller retreat stagger method of roller compacted concrete steps, then learned that the compaction test, the first measurement line, and then paving soil material, rolling, final quality inspection, but also adjust the content, we must pay special attention to the need for field compaction test soil, soil thickness, roller type and weight of machinery, rolling the number of times, the parameters of filling water content test. Test particle gradation of soil composite material, such as dry density test of compacted soil, particle size distribution is one of the main reasons affecting the compaction standard of maximum dry density and optimum water content, each parameter determines the success or failure of the test results, so in the course of the experiment in strict accordance with the requirements of control parameters, to ensure that each parameter qualified, then according to the test results of standard times best, in order to provide a scientific Shifosi Reservoir, data real, and put forward Relevant recommendations, so as to achieve a reasonable technical standards, and further get the desired results
In this paper, the research ideas, research methods and conclusions can be used for reference and reference for similar reservoir projects, so as to provide a more flexible and diverse solutions for the design and construction of the reservoir
