摘要
介绍了真空预压法加固软基的机理 ,并重点研究了该方法对加固区边界的影响 ,结合深圳河真空预压加固软基工程实例 ,采用平面应变有限元进行理论计算 ,计算中考虑了软土的流变特性和施工扰动对结构损伤的影响 ,并用实测结果来检验计算 。
The principle of consolidating the soft soil of foundation by vacuum preloading method is introduced.The effect of this method on the boundary of consolidated foundation is studied by using plane strain FEM taking the strength reduction due to the influence of construction and rheological behaveior into account.The calculated result of an example is in good agreement with observation data in situ.
