摘要
笔者合成了一种具有抑制膨胀土膨胀性的固化液 ,按不同比例向膨胀土内添加固化液 ,并用添加固化液后的膨胀土击实成试样 ,根据不同条件对试样进行保湿养护 ,随后又对试样进行了浸水试验、浸水后无侧限抗压强度试验、直接快剪试验 ,试验结果表明其固化膨胀土的水稳定性比膨胀土的好 ,浸水后的强度比膨胀土浸水后的强度高。
A kind of chemicals was synthesized by the authors,and it is added in expansive soil with different proportion.These specimen made of expansive soil improved by chemicals are cured and then submerged under water in a container.unconfined compression and direct shear tests are carried out,and the tests indicate that stability and strength of expansive soil improved by chemicals and submerged are better and greater than those of the original expansive soil submerged respectively.The test results are useful to engineering practice.
