Salt lake area roadbed construction method based on filler salt expansion critical moisture content measurement
The invention discloses a salt lake area roadbed construction method based on filler salt expansion critical moisture content measurement. The method comprises the steps that S1, the salt expansion critical moisture content of filler containing sulfate rock salt is determined; the optimal water content is determined; s2, carrying out salt lake area roadbed construction by taking the soil with the optimal water content and/or below the optimal water content as roadbed filler; the method comprises the following steps: S1, preparing a plurality of salt rock filler samples by taking the requirement of the application part of the salt rock filler in the roadbed on the compaction degree as the sample compaction degree and taking the optimal water content as the initial water content, respectively airing to different water contents, and then carrying out a salt expansion test; taking the environment temperature range of the salt rock filler in the roadbed as a test environment temperature range, controlling the change of the test environment temperature, and recording the volume change of the plurality of salt rock filler samples; setting the volume expansion not more than 1% as the qualified standard of the salt rock filler, and setting the initial water content of the sample corresponding to the standard at the beginning of the test as the optimal water content. The invention further discloses a corresponding construction system.
本发明公开一种基于填料盐胀临界含水率测定的盐湖区路基施工方法，包括：S1，确定含硫酸盐盐岩的填料盐胀临界含水率；并确定最优含水率；S2，将具有最优含水率和/或最优含水率以下的作为路基填料进行盐湖区路基施工；S1包括：以盐岩填料在路基中应用的部位对压实度的要求作为试样压实度，以最优含水率为初始含水率，制备多个盐岩填料试样，分别晾晒至不同含水率后进行盐胀试验；以盐岩填料在路基中所处的环境温度范围作为试验环境温度范围，控制试验环境温度改变，同时记录多个盐岩填料试样的体积变化；设定体积膨胀不超过1%作为盐岩填料合格的标准，达到标准所对应的试样在试验最初设定的初始含水率为最优含水率。还公开了对应的施工系统。
