Abstract:
There is an obvious yield stress for struclural solt soil, and extemal disturbanees result yield stressdecrease and compression inerease. Five-seelion line was used to simulate the compression curve of disturbedsoil, and virtual pre-consolidation pressure was put up aler the varied characteristies of pore ratio and stresswere analyzed in the proeess of deformation. Disturbed degree of solt soil that defined of logarithmie form waselosely connected with e-lgp curve, and thus conduetive to strength caleulation and deformation analysis of dis.turbed soil. Engineering praeliee showed that inadequate consolidation of soft soil should be considered whendisturbanee degree was ealeulated, and this method in the assay could reasonably prediet the ultimate setlle-ment of disturbed soil.
