环氧树脂改性材料在松软路面固化工程中的应用研究

Research on the application of epoxy resin modified material in the solidification engineering of soft ground

介绍了环氧树脂固化剂与其固化机理。重点进行复合固化材料在沙滩和淤泥这2种松软地面道路工程中的应用研究,分别设计了沙滩地面固化力学强度测试和淤泥地面固化稳定性测试,探究了试验设计方案与试样制备流程。结果表明:利用复合固化材料进行松软地面的加固,能够迅速使其具备较高的力学强度,可满足通用车辆的基本通行要求;复合固化材料的添加能够提升淤泥路面的整体稳定性,相比于只掺有水泥的固化淤泥,掺有复合固化材料的固化淤泥表现出较好的耐久性。

The curing agent of epoxy resin and its curing mechanism were introduced.Focused on the application research of composite solidified materials in road engineering of two kinds of soft ground like sandy beach and slit ground.The mechanical strength test and the stability test of curing of both beach and slit ground were designed respectively,and the test design scheme and sample preparation process were explored.The test results showed that using composite curing materials for reinforcing soft ground could quickly give it higher mechanical strength,meeting the basic traffic requirements of general vehicles.The addition of composite curing material improved the overall stability of silt pavement.Compared with solidified silt only mixed with cement,solidified silt mixed with composite solidified material showed better durability.
