摘要
应用材料真实破裂过程分析RFPA系统,对横跨地表裂缝的墙体开裂过程进行了数值试验研究.对于地裂具有垂直活动性的情况,数值试验再现了墙体出现裂缝的位置、倾向、倾角和裂缝发展的过程.数值试验结果表明RFPA方法是地裂诱发墙体开裂机理和规律研究的有效工具.
In this paper,the cracking process of wall over ground fissures was studied by using the Realistic Failure Processes Analysis （RFPA） code. For the ground fissures with proneness to sedimentation, numerical tests visually reproduce the complete processes of wall cracking with the crack position, dip direction and dip angle. It can be seen from the numerical simulations that the RFPA^2D code is an effective and valid tool to analyze the laws and mechanism of wall cracking of wall caused by ground fissures.
