摘　　要：为补充不同侵蚀环境下高钙粉煤灰水泥土所表现的力学性能数据,通过室内模拟侵蚀试验,研究不同侵蚀环境对高钙粉煤灰水泥土力学特性影响的变化规律。试验结果表明:低浓度碱性环境对高钙粉煤灰水泥土的抗压强度有促进作用,而高浓度碱性环境对高钙粉煤灰水泥土结构有侵蚀破坏作用;Ca(OH)2溶液几乎不会侵蚀高钙粉煤灰水泥土结构;MgSO4对高钙粉煤灰水泥土结构有着明显侵蚀作用。In order to supplement the mechanical properties of high calcium fly ash cement soil under different erosive conditions,this topic attempts to incorporate high calcium fly ash into cement soil.Through the indoor simulated erosion test,the variation law of the influence of different erosion environments on the strength of high calcium fly ash cement soil was studied.The test results show that low-concentration alkaline environment promotes the compressive strength of high-calcium fly ash cement soil,while high-concentration alkaline environment has erosiondamage effect on high-calcium fly ash cement-soil structure;Ca(OH)2 solution hardly erosion of high-calcium fly ash cement-soil structure;MgSO4 has obvious erosion effect on high-calcium fly ash cement-soil structure.
