Method for calculating uplift coefficient of foundation pile
The invention relates to the field of geotechnical engineering design, in particular to a method for calculating the uplift coefficient of a foundation pile. Comprising the following steps that firstly, stress analysis is conducted on a pile side soil body unit according to the pile side soil body stress state of the compression-resistant foundation pile, and the pile side soil body unit horizontal stress and the pile side soil pressure coefficient of the compression-resistant foundation pile are deduced; secondly, according to the pile side soil stress state of the anti-pulling foundation pile, stress analysis is conducted on the pile side soil unit, and the pile side soil unit horizontal stress and the pile side soil pressure coefficient of the anti-pulling foundation pile are deduced; and then a foundation pile anti-pulling coefficient calculation formula is deduced according to the pile side soil pressure coefficient of the anti-pressing and anti-pulling foundation pile. According to the invention, the problem of inaccurate evaluation depending on experience in construction is solved.
本发明涉及岩土工程设计领域，是一种基桩抗拔系数的计算方法。包括以下步骤：首先根据抗压基桩的桩侧土体应力状态，对桩侧土体单元进行应力分析，推导出抗压基桩的桩侧土体单元水平应力及桩侧土压力系数；其次根据抗拔基桩的桩侧土体应力状态，对桩侧土体单元进行应力分析，推导出抗拔基桩的桩侧土体单元水平应力及桩侧土压力系数；然后根据抗压、抗拔基桩的桩侧土压力系数推导出基桩抗拔系数计算公式。本发明解决了施工中依靠经验评估不准确的问题。
