| 摘 要： | 水玻璃是目前广泛使用的化学灌浆材料，对岩土体有明显的固化效果。为了提高水玻璃的固化效果，对温度改性水玻璃溶液固化硫酸盐渍土与复合改性水玻璃固化硫酸盐渍土进行了试验研究，并通过无侧限抗压强度试验、X射线衍射试验以及电镜扫描试验，分析探讨了温度改性水玻璃与复合改性水玻璃固化盐渍土的机制。结果表明，温度改性与复合改性后，水玻璃的固化效果有明显的提升。

Experimental Study on the Mechanism of Modified Sodium Silicate Solidified Sulfuric Sulphate Saline Soil |
| |
| Abstract: | Sodium silicate is chemical grouting material that is widely used, and it has a significant curing effect to the rock. In order to improve the curing effect of sodium silicate, the temperature modified sodium silicate solution cured saline soil and composite modified sodium silicate curing saline soil were studied. And the mechanism of temperature modified sodium silicate and composite modified sodium silicate curing saline soil were discussed by unconfined compressive strength test, X-ray diffraction spectroscopy and microscopic test. The experimental results show that the curing effect of sodium silicate is obviously improved after temperature modification and compound modification. |
