嵌入层状岩体的抗滑桩受力计算方法研究

针对工程中经常遇到的抗滑桩嵌固地层比较复杂的情况，应用弹性地基梁初参数法，推导了上土下岩“m-K”法、层状地基“K-K”法的弹性抗滑桩内力、位移数学解析解，同时为了推广电子表格法在抗滑桩治理滑坡领域中的应用，运用Excel内嵌的VBA语言编写相关的计算表格，使计算更加透明化。工程实例表明:所提出的电子表格法可完成嵌入复杂地层抗滑桩的全部计算并绘出内力图形，可有效提高抗滑桩变位、内力分析效率和计算精度。

Research on Calculation Methods of Anti-slide Piles of Embedded Layer Rock Mass in Complex Formation

For the complex geological conditions often encountered during reinforcement of strata with common anti-slide piles, the mathematical analytical solution of internal force and displacement of elastic anti slide pile with rock below soil "m-K" method and layered soil "K-K" method is derived by the initial parameters meth of elastic foundation beam. Meanwhile in order to promote the application of spreadsheet method in the field of landslide treatment, Excel VBA embedded language writing the relevant calculation form provides more transparent computing. The engineering examples show that the proposed spreadsheet method can complete all calculation and draw internal force diagram for anti-slide piles embedded in complex strata, and can effectively improve the analysis efficiency and calculation accuracy of the displacement and internal force of the anti slide piles.
