| 摘 要： | 依托输变电项目工程,对高强高耐水土壤固化剂(HEC)应用于戈壁荒漠区3种典型土壤的固化效果进行了室内试验研究.试验以无侧限抗压强度要达到1.5 MPa为标准,分别对影响固化效果的养护龄期、固化剂掺量等因素进行了对比分析.结果表明,在养护龄期7d以上,固化剂掺量达到8％以上时,固化剂对3种土壤的固化效果能够达到设计要求.通过对固化样本的力学性能、渗透性能、干缩性能等测试后表明,样本的各项性能均能满足输变电线路工程的水土保持要求.

| Abstract: | Relying on power transmission and transformation project,a laboratory experiment was conductedto study the curing effectiveness of high strength and water stability earth consolidator(HEC)soil stabilizerapplied to three typical soils in the Gobi Desert region.The influence factors for the curing effectiveness suchas curing age and curing agent content were analyzed at the 1.5MPa unconfined compressive strength.Results from the laboratory tests show that the curing effectiveness of the three soils meets design requirementswhen curing period is more than 7days and hardener volume reaches 8% and above.The tests for mechanicalproperties,permeability performance and shrinkage performance indicate that all the performances of samplesmeet soil and water conservation requirements in transmission a line project. |
