环形水泥电杆力学性能试验形式及方法,我国标准(GB 4623—84)作了评尽的规定,其中锥形杆采用悬臂式,等径杆采用简支式。由于试验形式不同,加载方向各异。前者沿侧向加荷测试,后者沿垂直方向加荷测试。实践表明,锥形杆的悬臂侧向加荷试验方法能满足检测的实际要求,具有简捷方便等特点,但等径杆的简支垂直加荷测试方法有些问题尚有争议,因此,必须加以研究解决。存在问题主要有以下几个方面:首先,用简支垂直加荷方法进行测试,
The form and method of testing the mechanical properties of the ring-shaped cement poles have been exhausted by the Chinese standard (GB 4623-84), in which the tapered rods are cantilevered and the equal-diameter rods are simply supported. Due to the different test forms, the loading directions are different. The former is tested along the lateral loading and the latter is loaded along the vertical direction. The practice shows that the cantilever lateral loading test method of the tapered rod can meet the actual requirements of detection, and has the characteristics of simplicity and convenience. However, some problems of the simple support vertical load testing method of the equal diameter rod are still controversial. Therefore, it must be studied. solve. The existing problems mainly include the following aspects: First, tests are carried out using the simply supported vertical load method.
