XX建工設(shè)計(jì)研發(fā)大廈室外樁板式擋墻由主樓/M軸開始到培訓(xùn)中心后面。擋墻由ABC段組成，此段邊坡坡高為10.2~12.7m，坡長約20m。邊坡下部主要為強(qiáng)風(fēng)化~中風(fēng)化巖層，上部主要為人工填土約為7.0m，土質(zhì)邊坡陡傾角開挖邊坡易發(fā)生圓弧滑動(dòng)破壞。
擋墻基礎(chǔ)為5根人工挖孔樁，截面尺寸為1500*1800，樁距為5.0m。平均樁長約為17.0m~19.5m。其中懸空段約4.0m，土層段約4m，巖層段約10m。嵌入中風(fēng)化完整巖層不小于6.5m�；貛r石天然抗壓強(qiáng)度不小于6.3MPa。擋土板受地貌影響設(shè)置為梯形，坡度為0.05，高度約為10.0m~13.0m，板厚300mm。
