| 摘 要： | 通过对现行主要格型钢板桩抗倾覆稳定性分析方法进行分析研究的基础上,提出了一种新的分析计算方法,即“修正分离法”.假设格内填料的自重不直接参与抗倾,而是通过它对格壁产生侧向土压力和摩擦力来体现其参与抗倾工作的机制和程度,从而对传统的TVA分离法进行修正,给出了更为优化的计算方法.并通过实例计算,与现行5种方法的计算结果进行比较,验证了该计算方法的合理性和实用性.

| Abstract: | Through references and comparison of main current computations for stability against overturning of cellular steel sheet pile,a new calculation method,modified separation method,is raised: assuming that the gravity of the packing inside the cellular sheet does not directly participate in anti-overturning,instead,the mechanism and degree of anti-overturning are represented by the lateral pressure and friction of the soil against the wall of the cellular sheet,accordingly amendment is made to the traditionalT... |
