| 摘 要： | 水泥搅拌桩在软土地基加固工程中的应用非常广泛，但在不同地质条件下其设计参数和施工工艺有所不同，结合天津市某铁路专用线工程对水泥搅拌桩的设计参数和施工工艺进行了室内和现场试验，认为在处理过程中须选择水泥品种，掺入石膏粉外加剂不能提高强度，宜选用三喷六搅施工工艺。以上结论对类似工程有较好的参考价值。

| Abstract: | The application of cement-mixed piles to the consolidating projects of soft-soil foundations is very common and wide,but the construction techniques and design parameters in different geological conditions have to be different.With the project of a certain special railway in Tianjin as a practical example,laboratory tests and on-the-spot tests are made of the design parameters and construction techniques for cement-mixed piles during the construction of the special railway,which conclude that in the course ... |
