摘要
膨胀土作为一种特殊的黏性土引发了许多地基与边坡方面的问题。通过野外勘探及室内外测试,揭示膨胀土的结构和力学强度具有分带性和时效性,依此提出了膨胀土边坡设计中分带取值和试验方法。并对渠坡表面采取置换措施后,土体参数取值作了探讨。
Expansive soil, one of the special clay soils, had caused many problems to foundations and slopes. It was revealed that the structure and strength of the expansive soil in Nanyang basin were of zonation and timeliness. Accordingly, different design parameters and experiment methods were proposed in this paper. The mechanisms of replacement with non-expansive soil for canal slopes were discussed in details as well.
