Analysis of Stability and Reinforcement of Faults of Baihetan Arch Dam

Abstract:

With the deformation reinforcement theory (DRT), numerical simulation of Baihetan arch dam and foundation is carried out. According to the unbalanced forces distribution, fault F₁₈ and shear zone LS₃₃₁₈ are the key reinforcement regions and unbalanced force of each fault is the corresponding optimal reinforcement force which is to maintain a stable state. To verify the validity of the results of numerical simulation, geomechanical model test of Baihetan arch dam is carried out. By analyzing displacement of corresponding measuring point in the overloading process, and observing failure of transverse section at each elevation, the results show that the unbalanced force distribution of each fault is consistent with the damage law of faults in geomechanical model test.
