摘　　要：本文对具有两个水平槽(内设扁式液压顶)的墙体,在其顶部和切槽内受均匀荷载作用时,按弹性理论作了分析。根据试验室14片墙体试伴和五幢5～8层房屋中的试验结果,考虑开槽之间砌体所受的约束影响,提出了使用扁式液压顶试验方法确定砌体投限抗压强度的计算公式。本文为该试验方法在砖结构中的推广应用提供了可靠依据。In this paper, a masonry wall with two horizontal channels made for inserting flat jacks has been analyzed based on the theory of elasticity, while the wall was subjected to compressive loads applied both at top of the wall and inside the channels. According to the experimental results obtained from flat jack tests carried out on 14 brick masonry wall specimens in laboratory and 5 five-storeyed and eight-storeyed buildings in-situ, a formula has been derived for determining the ultimate compressive strength of brickwork by use of the flat jack test method in consideration of the restraining effects on the masonry walls between the two jacks.This investigation provides a reliable basis for extensive application of the flat jack test to brick masonry structures.
