摘要
本文对膨胀土在复杂应力状态下的吸、失水三向和单向变形性能进行了系统的分析和讨论，提出膨胀上不但具有应力路径的依附性，同时还具有初始含水量的依附性的新观点，并用试验结果给予了验证。此外，还提出了一些实用的变形计算公式以及设计计算参数，将膨胀土极其复杂的胀、缩变形性能用较简单的形式和参数给予概化描述，为膨胀土基和边坡的计算设计提供了一种简明的计算模式。
Systematic analyses are conducted herein on the 3 direction and sing le direction deformation behavious of expansive soil during absorbing and losing water under the condition of complicate stress. A new view is suggested thaL the expansive soil is provided not only with dependency on stress path, dependency on initial mois- ture content is also existing, which is verified by tests. Some practical formulas for calculating deformation and parameters for designing are also given. The complicated defoimation behaviours of expansive soil are generalized with simplified manner and parameters. A clear calculating model for the design of foundation and slope of expansive soil is presented.
