摘　　要：分别根据设计规范中主要推荐的等代墩基法、依据Mindlin解的Geddes法及等效作用分层总和法计算上海崇明老滧港南闸的群桩沉降,并与实测成果对比分析,结合各计算方法的特点,验证了各方法在本地区的适用性,最终证明等效作用分层总和法的计算成果与实测结果最为接近,但各方法的沉降计算成果都比实测值偏大。The settlement of pile groups at the South Gate of Chongming Laogang in Shanghai was calculated based on the main recommended equivalent pier foundation method in the design specifications,Geddes method based on Mindlin solution,and equivalent action layered sum method.The results were compared and analyzed with the measured values.Combined with the characteristics of each calculation method,the applicability of each method in the local area was verified.Finally,it was proved that the calculation results of the equivalent action layered sum method were closest to the measured results,but the settlement calculation results of each method were larger than the measured values.
