Method for calculating pile sinking soil plug height of open tubular pile in homogeneous soil
The invention provides a method for calculating the height of a pile sinking soil plug of an open tubular pile in homogeneous soil, in the pile sinking process of the tubular pile, the soil plug is subjected to the combined action of downward gravity G, downward friction F of the pile and upward supporting force N of a soil layer on the bottom surface of the soil plug, and when the stress of the soil plug just reaches a balanced state, G + F = Nm, the calculation formula of the gravity G, the friction force F and the foundation bearing capacity Nm is substituted into G + F = Nm and simplified to obtain a soil plug height formula, so that the soil plug height does not need to be actually measured, the cost is low, and a result can be obtained only through calculation; the height of the soil plug of the tubular pile in any homogeneous soil layer and at any pile sinking depth can be calculated; in addition, parameters used in the method can be obtained from conventional measurement or survey reports.
本发明提供了一种均质土中开口管桩沉桩土塞高度计算方法，管桩沉桩过程中土塞受到向下的重力G、桩向下的摩擦力F和土塞底面土层向上的支持力N的共同作用，当土塞受力刚好达到平衡状态时，有G+F＝Nm，将重力G、摩擦力F以及地基承载力Nm的计算公式代入G+F＝Nm并化简，得土塞高度公式，从而不需要对土塞高度进行实测，成本较低，只需进行计算就能得到结果；且本发明可计算在任意均质土层中和任意沉桩深度下的管桩土塞高度；此外，本发明用到的参数都可从常规测量或者勘察报告中获得。
