By the analogy simulation tests on Xingtai mine, the failure characteristics of overlying strata and its displacement regularity are studied. 筆者是通過相似模擬試驗對邢台礦的煤層上覆岩層破壞特徵及其位移變化規律和頂板的應力變化規律進行了研究。
The mechanical and failure characteristics of SFHPC beams in bending test can be described well by using fracture energy and flexural toughness indices together. 綜合利用斷裂能和彎曲韌性指標，才能更全面地描述混凝土在彎曲過程中的受力與破壞特徵。
