摘要
结合宜万同城快速通道公路桥梁施工项目的基本条件,针对软土地质较浅区域采用砂垫层施工方式,软土地质较深区域采用水泥搅拌桩施工方式,结合排水施工与反压护道施工,完成公路桥梁施工技术设计.通过对施工后各个分段沉降测定得出,采用以上技术使沉降能够得到有效控制,沉降值为5mm左右,未超过沉降容许值的上限,并且沉降差值为1 mm,未出现沉降不均匀现象,有效提高了公路桥梁的施工质量.
Abstract
Combined with the basic conditions of the highway bridge construction project,the sand cushion construction method is a-dopted for the shallow soft soil geological area,and the cement mixing pile construction method is adopted for the deep soft soil geolog-ical area.The highway bridge construction technology design is completed in combination with drainage construction and back pressure berm construction.By measuring the settlement of each section after construction,it was found that the abore technology can effectively control the settlement of highway bridges.The settlement value is about 5 mm,which does not exceed the upper limit of the allowable settlement value.The settlement difference is 1 mm,and there is no uneven settlement phenomenon,effectively improving the construc-tion quality of highway bridges.
