摘要
软土中的地表硬壳层具有含水量、孔隙比小，密度、变形模量大等特点，且分布面积广，对提高地基的承载能力和控制建筑物的沉降有着积极的影响。从分析其作用机理入手，详细阐述了硬壳层在受力方面和沉降方面相对下卧土层的优越性，并针对工程中的实际问题，结合外荷载的不同和硬壳层的补强，提出对硬壳层的合理利用。
For crust layer located in soft soil, the water content and void ratio are small while unit weight and modulus of deformation are great. It can improve the bearing capability greatly and decrease the settlement remarkably. It begins with analyzing mechanism of crust layer, the superiorities on increasing bearing capability and decreasing the settlement are described. It is pointed that the crust layers should be reasonable utilized according to different load and different types
