摘要
根据水中爆炸荷载的特点，应用能量准则和声学近似公式，计算出水压爆破作用于构筑物每层壁的等效静载。以声波在各层介质中传播时波速的加权平均值作为构筑物的平均声波波速，计算出结构自振频率。再考虑构筑物的强度和动力特性，以及预期的破坏程度，把每层介质假设为一独立的构筑物，提出了多层复合壁构筑物水压爆破药量计算的模型，并列举了工程实例。
According to the peculiarity of explosive load in water,by use of the energy criterion and the sound wave approximate formula,the equivalent static loading on every layer of the wall that is produced by water pressure blasting is calculated in this paper.It treats the weighted average sound velocity in different mediums as the average sound velocity in the structure,thus the natural frequency of the structure is calculated.Based on the intensity,the power character of the structure,and the expected destructive degree,regarding each layer as independent,a blasting formula of water pressure blasting for this structure is presented,and an engineering example is given.
