耳墙式桥台是一种较好的桥台形式,它比之T型、U型桥台则可节约圬工约24～50%。××线全线施工的耳墙式桥有46座,桥台高度(自基顶至台顶的高度)从3.8m至22m,台后路基填土高度有达18m的,耳墙长度自1.4m至4.8 m,其中4.0m至4.6m长耳墙有40个,4.8m长耳墙有66个。我们重点地调查和观察了有 The outrigger abutment is a good abutment form, which can save about 24 ~ 50% of the workforce compared with the T-shaped and U-shaped abutments. There are 46 bridge-type ridges on the entire line of xx line. The abutment height (height from the base to the top) is from 3.8m to 22m. The height of the embankment is 18m. The length of the ear wall is from 1.4m To 4.8 m, of which 40 are from 4.0 m to 4.6 m long and 66 are from 4.8 m long. We focused on the investigation and observation
