Description

Technical Field

[0001] The invention belongs to a method for calculating the compressive bearing capacity of concrete, in particular to a method for determining cracking of concrete at a transmission tower foundation. Background Art

[0002] The foundation of a transmission tower is an important component supporting the angle steel tower. When designing a transmission tower, it is often assumed that the tower base plate and the concrete foundation are tightly connected, that is, all contact areas between the tower base plate and the concrete are under compression and tension. However, due to construction errors of the tower foundation, material deformation, loose bolts, and other reasons, the tower base plate and the foundation of a transmission tower in operation often become detached. There are two main forms of detachment: (1) curling, that is, the tower base plate and the foundation are detached in one direction; (2) curling, that is, one corner of the tower base plate is detached from the foundation. When the tower base plate and the foundation are detached, it is often accompanied by concrete cracking. Concrete cracking seriously affects the operation safety of the transmission line. Therefore, finding a method to determine the cracking of the concrete of the transmission tower foundation and repairing the tower base plate and the foundation in advance before the tower base plate and the foundation are detached but before the concrete cracks are caused is of great economic significance to power grid companies.

[0003] At present, many scholars have analyzed the bearing capacity characteristics of tower base plates in the case of corrosion, detachment or eccentricity, and studied the effectiveness of welding reinforcement methods in improving the bearing capacity of tower base plates, but no research has been conducted on the bearing capacity of tower foundation concrete. Summary of the Invention

[0004] In view of this, the present invention aims to overcome the defects in the prior art and proposes a method for determining cracks in the foundation concrete of a transmission tower, which plays an important role in improving the operation and maintenance level of the foundation of a transmission tower.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] In a first aspect, the present invention provides a method for determining cracks in a transmission tower foundation concrete, comprising the following steps:

[0007] Step S1: Calculate the maximum local pressure F at the tower foundation n ;

[0008] Step S2: Calculate the local compression bottom area Ab of the tower foundation;

[0009] Step S3: Calculate the local compressive bearing capacity F of the tower foundation concrete based on the local compressive bottom area Ab of the tower foundation obtained in step S2 c ;

[0010] Step S4: Based on the maximum local pressure F of the tower foundation obtained in step S1 n and the local compressive bearing capacity F of the tower foundation concrete obtained in step S3c Assess the safety of tower foundation concrete.

[0011] Furthermore, the maximum local pressure F in step S1 n It is the sum of the weight of the ground conductor of one span length, the weight of ice at the maximum design ice thickness, the weight of hardware, the weight of insulators, the weight of the tower and the additional load during maintenance of the anchor line.
