SUBGRADE SETTLEMENT FITTING BETWEEN SMALL BRIDGE ABUTMENT AND BRIDGE CULVERT IN SOFTSOIL AREAS
- 
					    摘要: 软土地区桥台与桥涵之间产生较大的差异沉降, 影响使用.提出采用沉降拟合方法, 即根据复合地基的设计思想, 通过在桥台与桥涵部位采用不同置换率, 调整沉降量, 使其相近, 以达到减少沉降差的目的.Abstract: Based on the designing principle of settlement deformation control, settlement fitting has been adopted to resolve the differential settlements between small bridge abutment and bridge culvert in softsoil areas.-
