[提要] 以天津地區(qū)軟土為例,采用彈性抗力法,通過(guò)選取不同強(qiáng)度指標(biāo),分別采用水土分算、水土合算分析了支護(hù)結(jié)構(gòu)內(nèi)力、變形。采用直剪快剪強(qiáng)度水土合算與固結(jié)快剪強(qiáng)度水土分算計(jì)算得出的支護(hù)結(jié)構(gòu)彎矩、位移十分接近;而采用相同強(qiáng)度指標(biāo),水土分算比水土合算所得彎矩、位移大25%~35%。
[關(guān)鍵詞] 支護(hù)結(jié)構(gòu) 強(qiáng)度指標(biāo) 對(duì)比計(jì)算Adopting elastic-resisting method and different indexes of strength of soft clay in Tianjin, the inner forces and deformation of retaining structure are gained considering the water-soil together/departure calculating method. Using undrained shear strength and water-soil together, the results are much close to results of the consolidated undrained shear strength and water-soil departure. While using the same shearing strength indexes, the results of water-soil departure method are approximately 25%一35%larger than those of water-soil together.
Keywords: retaining structure; strength index; comparing calculation參 考 文 獻(xiàn)
