某高速公路地处软基,因防洪堤建设需在桥旁堆载,堆载可能引起软基承载力不足进而影响桩基,须进行加固。以此为工程背景,分析了软土地基上堆载对桩基的影响,并通过比较几种常见的加固措施,采取了合适的加固方法,由此得到的实践经验供类似工程借鉴。 An expressway is located in a soft ground. Due to the flood embankment construction needs to be piled up beside the bridge, the pile loading may cause insufficient bearing capacity of the soft foundation and thus affect the pile foundation and must be reinforced. Taking this as the engineering background, the influence of pile-loading on the pile foundation on soft soil foundation was analyzed. By comparing several common reinforcement measures, a suitable reinforcement method was adopted, and the practical experience gained from it was provided for reference to similar projects.
