预应力锚索抗滑桩设计方法优化研究

根据预应力锚索抗滑桩的结构受力特点，运用弹性地基梁法，抗滑桩与锚索的变形协调原理建立方程组。编写大量计算程序，快速计算出锚索拉力、桩身内力及位移。将计算结果与常用的设计计算方法进行比对，优化后的计算方法为工程建设节省了大量投资。自编的计算程序有利于推动此类方案的设计由粗放型向精细化、由单靠经验向更为科学的方向不断发展。该方法直观、方便、快捷且适用，有效控制投资，可为同类工程设计提供有益参考。

Study on Optimal Design Method of Anti-sliding Pile with Prestressed Anchoring Cable

According to the structure stress characteristics of anti-sliding with prestressed ancho- ring cable, Using the method of elastic foundation beam, equations were established basing on Anti-slide pile and anchor the principle of deformation coordination. A lot of calculation program was writed,which can quickly calculate anchor tension,the internal force and displacement of pile. By comparison the cal- culating results with the outcome of the common design calculation method, the optimal design method saved a lot of investment for project construction. Tthe calculation program is conducive that the design of this kind of scheme is driven by extensive model to intensive, from experience alone to a more scientific direction. This method is intuitive, convenient, fast andapplicable, control the investment effectively, provide a useful reference for similar engineering design.
