双排桩加固素填土高边坡方法研究

Research on Reinforce Method of Plain Fill High Slope by Double-Row Pile Structure

研究目的:本文通过对双排桩加固素填土高边坡治理的案例介绍及有限元分析,明确了在填土高边坡工程中,勘察、设计、施工及监测各领域应该注意的问题和解决方法。研究结论:1) 素填土边坡设计过程应与数值分析方法相互验证,提高设计成果的可靠性及合理性。2) 前后排桩桩身弯矩呈左右镜像的S型分布;3) 前桩承担了更大的剪力与弯矩,结构设计过程应对前桩进行加强。4) 本研究结论对同类岩土工程治理具有指导意义。

Research purpose: Through analyzing reinforce method of plain fill high slope by double-row pile structure, the author gets the problem and solution in investigation, design, construction and monitoring of the plain full high slope. Research conclusion: 1) The design process of plain fill slope should be mutually verified with the numerical analysis method, which is improving the reliability and rationality of the result. 2) It is found that the bending moment of the pile in front and rear row is an s-shaped distribution with left and right mirror images. 3) The front pile bears greater shear force and bending moment, so the front pile should be strengthened in the structural design process. 4) The conclusion of this study could guide the similar geotechnical engineering.
