摘要
Abstract
Excessive differential settlement at road-bridge transition sections tends to cause hazards such as vehicle bump at bridgehead,road damage,underground pipeline damage and so on.Measures for subgrade settlement control mainly include lightweight filling method,preloading method,replacement cushion method and composite foundation method.In view of two typical saturated soft soil geological conditions in the southern and northern parts of Nanjing Jiangxinzhou Island,appropriate post construction settlement treatment schemes for filled road sections were proposed respectively.The research results show that on the basis of coordinating the overall project schedule in integrated developed areas,applying surcharge preloading to subgrade using spoil from regional development projects to control bridgehead settlement is technically feasible and economically advantages.关键词
