，以及土工格室的衝突效果。

土工格室的側向束縛效果首要體現在兩個方麵:一是土丁格室對格室外土體所發生的摩阻效應；二er是shi土tu工gong格ge室shi對dui格ge網wang單dan元yuan內nei土tu體ti的de緊jin箍gu效xiao果guo。土tu工gong格ge室shi對dui填tian料liao供gong給gei了le較jiao大da的de側ce向xiang束shu縛fu效xiao果guo，格ge室shi側ce壁bi對dui填tian料liao發fa生sheng向xiang上shang的de衝chong突tu支zhi承cheng力li，構gou成cheng一yi個ge具ju有you較jiao大da彎wan拉la剛gang度du與yu抗kang剪jian強qiang度du的de複fu合he體ti。此ci複fu合he體ti可ke以yi阻zu隔ge應ying力li和he位wei移yi的de傳chuan遞di，然ran後hou可ke以yi柔rou性xing過guo渡du並bing和he諧xie半ban填tian半ban挖wa路lu基ji頂ding麵mian的de沉chen降jiang。並bing且qie，它ta對dui局ju部bu荷he載zai具ju有you網wang兜dou效xiao應ying
，使shi荷he載zai的de分fen布bu更geng為wei均jun勻yun。
