摘　　要：粉细砂在我国分布范围极广,但由于其具有无粘结性、无可塑性的特点,采用常规的路基压实设备碾压,难以达到压实效果,施工性能较差,故在工程实际应用中,直接采用粉细砂作为公路、铁路路基填料的案例较少。本文介绍了采用有约束碾压设备填筑粉细砂填料路基的施工技术和方法,并介绍了现场试验过程和在工程实例中取得的成果,对应用前景进行了分析。Abstract： Silty sand is widely distributed in China, but since it has no cohesiveness and plasticity, the conventional subgrade compaction equipment is difficult to achieve the compaction effect. So there are few cases using silty sand as the highway, railway subgrade packing in actual construction. This article introduced the construction technology and method of using constrained rolling equipment to fill silty sand packing subgrade, and introduced the field test process and results obtained in the engineering examples, and finally analyzed the prospect of application.
