摘　　要：河北省石家庄市南二环东延西拓工程为石家庄市城市快速路,该工程修建一座桥梁跨越总干渠,影响范围内渠道无法填筑及衬砌。按常规方法施工,工期难以满足要求。为保证缺口处填筑质量及衬砌质量,对缺口处填筑部位拟定了两种加强措施,将沉降期缩短。经过对比最终确定按方案一实施,即混凝土衬砌厚度不变,衬砌混凝土中掺加纤维素纤维,衬砌分缝变小。按确定的方案施工,保证了工程质量,满足了通水要求。Near the south east of Shijiazhuang city, Hebei Province, western extension works for the city of Shijiazhuang city expressway, the project to build a bridge across the canal, effects of channel can not filling and liner range. According to the conventional method of construction, construction period is difficult to meet the demand of. To ensure the quality of gap filling quality and lining. The gap filling parts designed two kinds of measures, the settlement period. After comparing thefinal implementation according to scheme 1, the thickness of lining concrete invariant, mixed withcellulose fiber concrete lining, lining seam smaller. In the case of construction to ensure engineering quality, to meet the water requirements.
