由于目前土石坝裂缝产生的评判及预测缺乏统一标准,本文采用FLAC3D中可以产生滑动和分离的接触面Interface单元作为土石坝内部的隐含破坏面,以此模拟土石坝裂缝开展,探讨裂缝评判方法。最后,用离心模型试验证明该方法用于模拟土石坝开裂的可行性与合理性。
Abstract：As the absence of the unite criteria for evaluating and predicting occurrence of cracks on rockfill dam at present,the interface elements in FLAC3D( Fast Lagrangian Analysis of Continua) those can cause sliding and separating are taken as the potential failure planes for simulating the cracking of rockfill dam and then probing into the method for judging the cracks. Finally,the feasibility and rationality of the application of this method to the simulation made on the cracking of rockfill dam are demonstrated by the centrifugal modeling test concerned.
