| Abstract: | 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 RFPA2D code is an effective and valid tool to analyze the laws and mechanism of wall cracking of wall caused by ground fissures. |
