We developed a distributed memory parallel program to simulate the failure of concrete walls under tsunami wave impacts. The program is validated by reproducing some experimentally observed crack patterns reported in literature. The validated program is used to successfully reproduce the observed crack patterns on full scale concrete wall models, tested at the Large Hydro-Geo Flume Facility (LHGF) of the Port and Airport Research Institute, using the experimentally observed pressure data as an input.

我们开发了一个分布式存储并行程序来模拟海啸冲击下混凝土墙的破坏。该方案是通过再现一些实验观察到的裂纹模式在文献报道验证。经过验证的程序成功地在全尺寸混凝土墙模型上复制了观察到的裂缝模式，并在港口和机场研究所的大型水力-土工水槽设施（LHGF）进行了测试，使用实验观察到的压力数据作为输入。
