冻土区建筑空间通风壳式基础的实验研究(英文)

The experimental research of the spatial ventilated shell-type foundations for construction in permafrost zone

对于空间建筑零循环通风壳式基础建设方案的无霜期敏感的土壤层,被认为是位于冻土和基础之间。基于固体变形体扩展相似理论的混凝土模型的调查结果以及在现场壳型基础自然片段。考虑基础结构的应力—应变状态,这取决于在弹性阶段地基土和脆性断裂阶段的变形阶段。

Constructive schemes of zero cycles of buildings on the spatial ventilated shell-type founda-tions at the intermediate layer from nonfrost-susceptible soil , which is located between the foundation and the base of frozen ground , have been considered .The results of investigations of concrete models based on the theory of extended similarity of solid deformed bodies have been given , as well as a natural frag-ment of shell-type foundation at the site .We consider the stress-strain state of foundation structures , depending on the deformation phases of the foundation soil in the elastic stage and the stage of brittle frac -ture.
