Method for calculating length of semi-steel casing of track connection engineering pile-slab structure roadbed
The invention relates to a method for calculating the length of a semi-steel casing of a track connection engineering pile-slab structure roadbed, and the method is characterized in that the method comprises the following steps: S1, inputting basic parameters; s2, the total pile length l, the pile distance d and the standard value of the pile side friction resistance are determined, if the pile distance is smaller than 6 times of the pile diameter, the step S3 is executed, and if the pile distance is larger than or equal to 6 times of the pile diameter, the step S4 is executed; s3, calculating a pile group effect coefficient eta; s4, determining correction coefficients zeta, lambda 1, lambda, k1 and k2; s5, substituting the obtained data into a formula of the length of the pile body occupied by the semi-steel pile casing; and S6, outputting a result h1. Compared with the prior art, different calculation methods are adopted for a single pile or a pile group, the length of the steel pile casing can be more accurately determined by analyzing mechanics, pile group effect and the like in the optimal proportion calculation of the length of the pile body occupied by the semi-steel pile casing, the material utilization rate is effectively increased, and the construction cost is reduced; and the function of downward transfer of pile side frictional resistance during operation is met.
本发明涉及一种接轨工程桩板结构路基的半钢护筒长度计算方法，其特征在于，包括以下步骤：S1输入基本参数；S2确定总桩长l、桩间距d和桩侧摩阻力的标准值，若桩间距小于6倍桩径，执行步骤S3，若桩间距大于或等于6倍桩径，执行步骤S4；S3计算群桩效应系数η；S4确定修正系数ζ、λ1、λ、k1、k2；S5将所得的数据代入半钢护筒所占桩身长度公式；S6输出结果h1。与现有技术相比，本发明对于单桩或者群桩采用不同的计算方法，在半钢护筒所占桩身长度的最优比例计算中通过对力学及群桩效应等多方面分析，更能准确的确定钢护筒长度，有效提高材料利用率，降低工程造价，满足运营期间桩侧摩阻力向下转移的功能。
