Abstract  In this review, the tunnel engineering geological disasters were firstly reported, and then the simulation applications of tunnel engineering related to RFPA were summarized. The following main conclusions were that during the construction of tunnel engineering, the tunnel engineering of main geology disaster types including solid geological disasters, quasi fluid geological disasters and fluid geological disasters; the RFPA numerical methods in tunnel engineering construction related rock mechanics and failure characteristics of acquiring, under the condition of excavation of tunnel damage simulation, bedding rock tunnel excavation simulation, dynamic tunnel under the condition of failure simulation, simulation and partition of deep surrounding rock fracture under the action of seepage tunnel stability analysis were carried out in such aspects as widespread application; at present, RFPA has made important progress in the aspects of calculation accuracy, calculation scale and calculation speed, parallel computation of large-scale solution process, construction of numerical computing cloud platform and so on. It is believed that with the continuous development of technology and program, RFPA numerical calculation method will be more widely used in tunnel engineering simulation.
