The stress condition; overall stability; effect of filling gravels into the hole of the block of the precast concrete interlocking blocks in the water flow during the flood period as well as the resistance parameters of the blocks are studied through experimental simulation; in which a comprehensive analysis is made on the mechanical stability and the anti-erosion properties of the blocks, and then the requirement and the safety degree of the gravel filling are given 摘要通過試驗(yàn)?zāi)M研究了預(yù)制混凝土連鎖塊在洪水期水流中的受力狀況、整體穩(wěn)定性、孔內(nèi)填充碎石的作用及連鎖塊阻力參數(shù),綜合分析了連鎖塊結(jié)構(gòu)的力學(xué)穩(wěn)定性和抗沖性,給出了碎石填充的要求及安全度。
