| 6. | According to the character that the soil can endure the press than the tensile strength , the arching shape of the soil arch between piles has been regarded as the reasonable arch axes . by analyzing the mechanical balance condition of the arch , the transfer mechanism of the thrust has been gained . at the same time , the formula for computing the thrust acting on the pile has been gotten , and the present computing formula is just the special example of it 根据岩土体抗压性好、抗拉性差的特点,将桩间土拱的拱形视为合理拱轴线方程,通过分析土拱的力学平衡条件,得出桩间滑坡推力的传递模型,并由此得到抗滑桩上的滑坡推力计算公式,现有抗滑桩上滑坡推力的计算公式只是本文公式的特例。 |
