港池爆炸兴波响应的计算方法

本文以爆炸兴波的ＭＡＣ法轴对称计算结果为初值，提出了对于实际港池后期兴波响应的两种计算方法。其一是基于溶器内液体驻留运动的振型叠加法，其二是爆炸早期兴波与浅水波理论的时域衔接法。进行了一千吨ＴＮＴ当量在港池内触水爆兴波的实例计算。计算表明，该方法能够合理地描述波浪演化特征，与爆炸现场的景观相吻合，可为工程设计提供简易、实用的结果。

CALCULATION METHODS FOR RESPORSE OF WAVEMAKING BY EXPLOSION IN HARBOUR

In this paper, two calculation methods for late response of wavemaking by explosion in harbour are proposed by mens of axial symmetry results of the MAC method as the initial value. One of the methods in the superposition of vibration mode based on the fluid slosh in a container;another one is the joining method of the MAC results with the shallow wave theory calculation in time domain.As a practical example,the numerical calculations of 1000 ton TNT equivalent explosion touch on the water surface are carried out. The numerical results are consistent with the observed scence of the spot experiment. The methods are rational,simple and applicable for engineering design.
