天然双层软土地基硬壳层的作用机理研究

Research of Affecting Mechanism of Harden Surface Layer on Natural Double Soft Soil Foundation

硬壳层的存在改变了地基的受力状况,使地基土变为双层的受力模式。通过深入的理论研究,提出硬壳层软土地基界面附加应力的分布规律、硬壳层对地基附加应力的扩散,有助于确定科学合理的地基处理方案,从而节省投资和缩短工期。

Harden surface layer changes the stress of base, which brings about the double stress mode of foundation soil. Based on the profound theory research, in this paper are distribution rule and diffusion of additive stress produced by harden surface layer to soft foundation, which is beneficial to deciding on scientific and proper foundation disposal scheme, thus saves investment and shorten the construction period.
