Abstract

The minimum socket depth for circular pipe pier-bearing platform socket connection can be calculated according to Article C.0.3 in the Specifications for Design of Highway Precast Concrete Bridges (JTG/T 3365 -05—2022 ).In order to enable engineering designers to fully understand and correctly apply the calculation formula in this article,this paper first introduced the main technical features of the typical connection scheme,as well as the structural failure principles and objectives formulated in the specification of the typical connection scheme.Then,it briefly introduced the experimental research content and results of the typical connection scheme and explained the key construction measures and their functions of the typical connection scheme.Finally,the paper compared the minimum socket depth estimation formula in the specification with experimental research.The results indicate that on the premise of meeting the main technical characteristics and construction requirements of the typical connection scheme,the minimum socket depth calculated according to the relevant formulas in the specifications can meet the structural failure principles and objectives of the typical connection scheme and has a certain safety reserve.
