Dynamic correction method for controlling hammering penetration during hammering pile construction

According to the dynamic correction formula for controlling the hammering penetration during hammering pile construction, dynamic correction can be conducted according to the deviation condition of the actual pile length during construction, and a penetration constant value control method commonly used in current engineering practice is changed into a dynamic correction method. The correction method comprises the following steps that A, a designed single pile bearing capacity characteristic value # imgabs0 # is obtained, and the unit of the characteristic value # imgabs0 # is kN; step B, a single pile bearing capacity characteristic value # imgabs1 # is obtained and calculated, the unit of the characteristic value # imgabs1 # is kN, and the value is obtained through calculation according to the actual pile length and soil layer parameters provided by a geological survey report; c, according to the design drawing, the penetration control index # imgabs2 # of each of the last three arrays is obtained, and the u
