大桩距组合砖砌体承台梁受力性能的试验研究

Experimental Research on Behavior of Reinforced Concrete-Brick Masonry Pile Capping Beam with Large Pile Spacing

本文结合工程设计，提出采用钢筋砼和粘土砖砌体组合成一种新的受弯构件型式，用于砼桩基础的承台梁。９根试件的试验研究表明，新型梁共同工作性能良好，技术经济指标先进，值得进一步研究和应用。

In combination with the structural design of an engineering project,a new type of fie-cural member--the composite reinforced concrete and brick masonry was used as pile capping beam of pile foundation.The test results of 9 specimens show that the reinforced concrete and brick masonry composite members possesse xcellent interactive working behavior.The application of such structure in engineering practice has proved to ho advanced in technology and economical in construction cost.
