摘要
在对滑坡工程中全埋式抗滑桩间土拱效应分析的基础上,提出了以桩间静力平衡条件、跨中截面强度条件以及拱脚处截面强度条件共同控制来确定桩间距,得到了较为合理的桩间距的计算公式,定量地说明了在其他因素不变的情况下,桩间距随桩后土体粘聚力或内摩擦角的增大而增大,却随着桩后坡体推力的增大而减小。最后,以工程实例说明了桩间距的计算过程并得到了比较合理的计算结果。
Anti-sliding pile has been used for prevention and cure landshde 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.
