在单桩水平承载力研究中,通常忽略承台的作用,这样使求解的过程得以简化,但在实际应用中承台的作用是不容忽视的。利用计算机可以很方便地模拟单桩的水平受力情况,可以节约大量试验经费和工期,也能保证一定的精确度。文章用ABAQUS模拟没有承台以及有承台而承台大小、埋深不同时桩的水平受力情况,发现承台对提高单桩水平承载力的贡献很大,且大小、埋深不同时,这种贡献也不同。 In the study of horizontal bearing capacity of single pile, the function of cap is usually neglected, which simplifies the solving process, but the function of cap should not be neglected in practice. The use of computer can easily simulate the level of single-pile stress, you can save a lot of experimental funding and construction time, but also to ensure a certain degree of accuracy. The article uses ABAQUS to simulate the horizontal force of piles without cap and cap with the size and depth of piles. It is found that the cap contributes a lot to the horizontal bearing capacity of single piles, and when the size and depth are different, This contribution is also different.
