开孔垂直连锁混凝土砌块专用混凝土强度公式的建立

Development of Strength Formula for Perforated Vertical-chained Concrete Block

鉴于南水北调东线一期工程有3座平原水库施工应用开孔垂直连锁混凝土砌块护坡技术,为了对砌块抗压强度进行快速、准确地检测,采用钻芯法与回弹法相结合的方法,建立开孔垂直连锁混凝土砌块专用混凝土强度公式,可用于砌块强度的检测。

In the first stage of the east route of south-to-north water diversion project , the technology of perforated verti-cal-chained concrete block revetment has been used in the construction of three plain reservoirs .To measure the com-pressive strength of the block accurately and rapidly , a combination scheme with the core drilling technique and the re-bound method are adopted .Then a special formula is developed for the compressive strength of perforated vertical -chained concrete block .
