道路桥梁工程中软土地基常见问题处理措施 Common problems and treatment measures for soft soil foundation in road and Bridge Engineering 　不同地区软土地基由于土体不同，土层不同相应的土体也不同，导致软土地基性质存在很大差异。施工过程中出现的质量事故大多与设计施工人员弄不清楚软土地区地质实际情况息息相关，尤其对于道路桥梁工程来说更是如此。桥梁工程中的软土地基由于受到工程性质和土质的影响，其软硬程度存在很大差异。因此，一个科学可行的施工方案应考虑到不同地区的软土实际情况，参照具体工程标准，对实际问题实施具有针对性的处理措施。下文首先阐述桥梁工程中软土地基常见问题和施工现状，在此基础上提出几种常用的软土地基施工处理措施，以期最大程度保证道路桥梁工程施工质量。 Different regions due to different soft soil foundation soil, soil layer at different corresponding different too, cause there is a big difference in properties of soft soil foundation. Quality accident in the process of construction and most of the design and construction personnel did not know the actual situation of soft soil area is closely related to geology, especially for road and bridge engineering is so. Bridge engineering in soft soil foundation due to the influence of the nature of the project and the soil, the great difference of the degree of hardness. Therefore, a scientific and feasible construction scheme should take into account the different regions of the soft soil conditions, the specific reference to engineering standards, the implementation of the corresponding treatment measures on practical issues. The following paper, soft soil foundation in bridge engineering problems and construction status, on the basis of several commonly used soft soil foundation construction measures, with a view to the greatest extent to ensure the construction quality of road and bridge engineering. 　　一、道路桥梁工程中软土地基的常见问题及施工现状 Common problems and present situation of construction, road and Bridge Engineering in soft ground 　　软土地基的性质随所在地区不同而不同，同时不同土层软土地基性质也不尽相同，因此不可预见性较大。在设计及施工过程中，很容易出现质量事故，主要包括以下几种：勘察工作不到位导致未对该作软土地基处理的地段作认真处理，此类案例不胜枚举；虽勘察出是软土地基，但未做认真处理，导致路堤不稳，甚至对线外建筑物产生威胁；即使作了软土地基处理，但由于施工处理措施不当，同样照成了路堤不稳；分层填筑没有严格按照工程规定，导致填土速度过快，碾压不当，进一步造成了路堤失稳；填筑不当破坏了“硬果层”导致路堤失稳，这个问题对道路桥梁工程的影响尤为严重。 Properties of soft soil foundation with the area is different, and different soil properties of soft soil foundation
