Empirical model of concrete block fragment behavior under explosion loads
《Science China(Technological Sciences)》2024年第8期2515-2529,共15页YANG Shuai NING JianGuo REN HuiLan XU XiangZhao 
supported by the National Natural Science Foundation of China (Grant Nos. 12032006 and 12372350)。
Concrete structures undergo integral fragmentation under explosion loads. The fragmentation degree and particle-size distribution of concrete blocks under explosion loads must be considered during mining to ensure saf...
