【摘要】 主要研究了房屋产生裂纹的原因,及爆破震动对民房影响的大小。计算并测定爆破时邻近村庄的最大地面质点振速,寻求保证该村居民建(构)筑物安全的最大单响药量,同时研究扩大爆破规模时的降震措施。更多还原

【Abstract】 The test mainly studies some reasons why houses appear cracks,and the influence of blasting vibration to house.We calculated and measured the biggest vibration velocity of villages near the explosion place,and explore the largest quantities of once blasting which made sure the building to be safe.Meanwhile,measures of declining vibration speed were studied when extended explosion scale.更多还原
