Method for calculating specification of eight-anchor-bolt rigid tower base plate for power transmission tower
The method discloses a method for calculating a specification of an eight-anchor-bolt rigid tower base plate for a power transmission tower. The method comprises: firstly, calculating a down force applied to the rigid tower base plate and an uplifting force applied to each anchor bolt so as to obtain the diameter of each anchor bolt, then calculating the minimum width of the rigid tower base plate, and calculating the minimum thickness required by pressure application and a minimum thickness required by pulling force application. According to the method, by using infinite element analysis and by means of infinite element analysis software, data is fitted; a concept of equivalent force arm computation is introduced, the influence of a base plate on a geometric force arm is considered, and subtraction is performed on the geometric force arm, so that the bearing capability of the tower base plate is reflected truely; the extreme bearing capability, calculated by the method, of the rigid tower base plates with the same specification is greater than a calculation numerical value in the (technical specification) and is smaller than an experimental value; and while the method overcomes the defects of the (technical specification), the calculation result is more reasonable and more reliable.
