1.绪言一般情况下,对于受水平力的垂直桩来说,如桩前面地基水平面较大范围有抗力时,应按三维问题来分析。但考虑桩和地基为整体时,一般多作为二维问题来分析。这可以北上川北上大坝工程中,坝墩施工时所用的临时防水围堰作为例子。临时围堰内外水位差作用在坝墩桩基上,其受力情况用有限元法分析。此时,荷载作用的长度要比宽度大,所以地基可
1. INTRODUCTION Under normal circumstances, for horizontal piles under horizontal force, if there is resistance over a wide range of water level in front of the piles, they should be analyzed according to three-dimensional problems. However, considering the pile and the foundation as a whole, it is usually analyzed as a two-dimensional problem. This can be north of the North Sichuan dam project, construction of temporary pier used in temporary waterproof cofferdam as an example. Temporary cofferdam water level difference between inside and outside the role of the dam pier foundation, the force situation using finite element analysis. At this point, the length of the load is greater than the width, so the foundation can be
