Anti-streaming sliding sparse pile type highway composite soft soil foundation and design method thereof
The invention discloses an anti-streaming sliding sparse pile type highway composite soft soil foundation and a design method thereof, and belongs to the technical field of soft foundation treatment, and the anti-streaming sliding sparse pile type highway composite soft soil foundation comprises a fill embankment, a reinforced drainage cushion layer, a plurality of prefabricated rigid piles, a soft soil foundation and a plurality of prefabricated insertion plates. A plurality of lateral reinforcement bodies are formed in the highway soft soil foundation by changing the shape of the section of the pile body and additionally arranging the vertical prefabricated insertion plates, the pile distance and the pile diameter do not need to be continuously increased under the condition that embankment filling meets the stable overall shear sliding condition, the restraining effect of lateral passive soil pressure of a soil body on streaming sliding is fully exerted, and the stability of the embankment filling is improved. The function requirement of resisting streaming sliding is met; and the structure prefabrication degree is high, construction is convenient, the design method is simple and reliable in principle, and operation is convenient.
本发明公开了一种抗绕流滑动疏桩型公路复合软土地基及其设计方法，属于软弱地基处理技术领域，包括填方路堤、加筋排水垫层、多个预制刚性桩、软土地基、多个预制插板。本发明通过改变桩身截面形状与增设竖向预制插板在公路软土地基中形成了数道侧向增强体，可在路堤填土满足整体剪切滑移稳定的条件下，无需继续加密桩距、增大桩径，充分发挥土体的侧向被动土压力对绕流滑动的抑制作用，满足抗绕流滑动的功能需求；并且结构预制化程度高，施工便捷，设计方法原理简明可靠，便于操作。
