建筑中,由于设置闸门或水流等条件限制,挡土墙墙面常需做成铅直面,故多采用俯斜式(图1)。 挡土墙常用砌石或混凝土建造。为了改善基底压力状态,常将基础宽度适当扩大,两端向外伸出,使基底压力减小并力求分布接近均匀。重力式挡土墙可就地取材,施工简单。由于其体积和重量较大,建筑高度往往受地基容许承载力的限制,即使地基承载力允许,过高将耗费较多材料,也不经济,故常在挡土高度5一6米以下时采用。当墙高超过5一6米时,常将墙身局部挖空代之以填土,也可做成有减压台的衡重式挡土墙(图2)或半重力式挡土墙,借以节约材料。衡重式挡土墙由直墙、减压台与底脚3部分组成,其特点是利用减压台支承上部填土,以减小减压台以下墙背所受的土压力,有助于挡土墙的稳定,同时使基底压力分布均匀。半重力式挡土墙是将重力式墙身断面缩小,基底放宽,既减小基底压力,也节省混凝土,减压台底脚图2衡重式档土墙而在局部拉应力较大处配置少量钢筋。重力式挡土墙墙后及墙身常需设置排水设备,并每隔一定距离设伸缩沉陷缝。如有防渗要求,缝内应设止水。 (陈德亮)zhonglishi da重力式挡土竖u吧ng徊LgraVILy fetalnlllg Wall)主要依靠自重维持稳定的挡土结构。是挡土墙最常用的型式之一。一般做成简单的梯形断面。根据墙背的坡度,重力式挡土墙分为仰斜、垂直及俯斜3种型式。挖方处的挡土墙,一般作成仰斜式,施工方便,土压力较小,墙身截面比较经济;填方处的挡土墙,墙背需回填土,常采用俯图l斜式和垂直式,使填土易于夯实。重力式挡土墙在水闸等一些水工
