摘要
分析路堤下柔性桩复合地基的荷载传递,寻找一个位移函数,得到有效桩长的计算公式。通过实例验证与对比分析,结果表明:有效桩长理论值非常接近实测值且稍微偏大,而其他方法都是比实测值偏小。该有效桩长理论计算是合理有效的且偏于安全的,对以后该种工程具有一定的参考意义。
Load transfer of deformable piles is analyzed by displacement function which is quested for. And new simplified formulas of effective length of pile are deduced. Through practical engineering and contrastive analysis, it is found that the theoretical value of effective length of pile is close to and a little greater than observation of test, where as it is less than observation of test by using the other methods. So the present formulas are reasonable and safety, which provides some reference for that kind of engineering practice.
