【摘要】 抗滑桩最大桩间距确定的基础理论至今未建立起来 ,工程实践中仍依赖专家经验。本文从方桩桩间土拱形成的原理、力学特性论证入手 ,较全面地分析了桩间土拱的受力、变形 ,力的传递和土拱破坏瞬间的最大桩间距。并建立了最大桩间距平面计算模型更多还原

【Abstract】 Anti sliding pile has been used for prevention and cure landslide more than 40 year, but the radical theory to decide the max distance of one another pile hasn’t been set up to now, and the suitable distance of one another depend mostly on expert’s experience to decide in work. The paper start from the principle and the mechanical characteristic of forming soil arch of square pile, and analysis roundly the power and the deformation and of soil arch between two anti sliding pile, and the instant most distance between two piles when soil arch is been destroyed as well as, also set up the plane model to decide the suitable distance between two piles.更多还原
