松木桩适宜在地下水位下的环境工作,适用于河道内、河岸边、鱼塘附近及地基含水量高、软土地基厚度不大的工程。文中结合京沪高速铁路清沧特大桥跨越子牙新河支架现浇梁软弱地基,采用松木桩处理的实例介绍表明,松木桩是一种取材容易、施工简便、造价低廉的软土加固技术,只要使用得当,效果良好。 Pine stakes suitable for environmental work under the water table, apply to the river, river banks, fish ponds and foundation near the high water content, soft ground thickness is not large projects. In this paper, Beijing-Shanghai high-speed railway bridge across the Qinghai-Cangkang special bridge cast-in-place beam weak foundation, the pine stump treatment example shows that the pine stump is a material easy, simple construction, low cost soft soil reinforcement technology, As long as properly used, the effect is good.
