用于配筋砌块挡土墙的开槽砌块灌孔砌体力学性能试验研究

摘要

Retaining wall construction is an important part of highway construction,Using the new reinforced concrete block retaining wall will Save the human and material resources consumed by road construction,and speed up the construction speed,save highway construction investment.In this paper, 9 compressive specimens and 18 shear specimens were tested to investigate the compressive strength, shear strength and failure mode of the grouted slotted block masonry,to investigate the impact of slotted block on the Mechanical Properties of grouted block masonry.The results show that the compressive ulti-mate load and shear strength of the grouted slotted block masonry is both improved,and the improvement of shear strength is more apparent.%挡土墙建设是高速公路建设中的重要组成部分，采用新型的配筋砌块挡土墙将节省我国公路建设所消耗的各项人力、物力资源，并加快施工速度，节省公路施工成本。针对配筋砌块挡土墙中广泛使用的开槽砌块，通过9个抗压试件、18个抗剪试件的静力试验，了解开槽砌块灌孔砌体的抗压强度、抗剪强度及破坏模式等力学性能，探讨砌块开槽对灌孔砌体力学性能的影响。试验结果表明，与普通砌块灌孔砌体相比，开槽砌块灌孔砌体的抗压承载力与抗剪强度均有一定的提高，而抗剪强度的提高更明显，其整体性更好，更适合在挡土墙中使用。
