基于施工过程的土石围堰应力应变分析

alculating and simulating the stress and deformation of Rockfill cofferdam with Ducan model, considering with the character of cofferdam construction. Through analyzing stresses and deformations, educed the settlement and pricipal stress state of all construction stages and concluded the relative orderliness. Through the comparision of construct-considering operating condition and no- construct-considering operating condition, educed the influence orderliness of construction process to the stresses and deformations of Rockfill cofferdam.
