摘要

针对含硫酸盐介质的环境水服役条件，通过室内模拟试验手段，研究了不同配合比参数和不同条件下水泥土的无侧限强度、弹性模量以及应力-应变的变化规律，分析了硫酸盐侵蚀环境下水泥土力学性能的劣化机理。结果表明，配合比参数以及环境条件对水泥土的无侧限抗压强度、弹性模量、应力-应变曲线有显著的影响；硫酸盐溶液中的水、硫酸根离子与水泥土之间的复杂物理、化学作用，影响水泥土内部微细观结构，从而对水泥土的力学性能存在显著劣化作用；且这种侵蚀作用在90d龄期内最为显著。

Abstract

Based on the service ambient with sulflate condition

the evolution of strength unconfining

elastic modulus and stress-strain curve of corresponding samples under various conditions are investigated by experimental simulation method; the deterioration of mechanical properties of soil cement is also studied. Results show that the parameters of different rations of cement to soil and different water contents and ambient condition have great influence on strength and elastic modulus of soil cement. The mechanical behaviors such as compressive strength and elastic modulus of soil cement can be degraded by underground water with sulfate due to complicated physicochemical reaction between soil cement and water and sulfate ion in ambient. And the bad effects of sulfate ion in ambient on mechanical behaviors of soil cement is prominent within 90 d ages.
