【 摘 要 】
The collapsibility test in field may have huge error with computed results[1-4]. The writer gave a compare between single-line and double-line method and then compared with the field's result. The writer's purpose is to reduce the error of measured value to computed value and propose a way to decrease the error through consider the matric suction's influence to unsaturated soil in using finite element analysis, field test was completed to verify the reasonability of this method and get some regulate of development of collapse deformation and supply some calculation basis of engineering design and forecast in emergency situation.
