..., angle, buried depth, and pipe diameter were investigated, respectively. The results show that in the actual project, the advance jacked pipes have amplification and superposition effects on friction resistance of the subsequent pipe, and the maximum growth rate is 37.2%. The friction resistance...

... of sequences of earthquakes and aseismic slip for both compressive and tensile stepovers with off‐fault plasticity. We consider a rate‐and‐state friction law for the fault friction and pressure‐sensitive Drucker–Prager plasticity for the off‐fault bulk response. We observe that the accumulation of plastic...

... that the conditions for self‐arrested ruptures are connected to the decrease of residual energy at rupture boundaries. The simulations utilize the linear slip‐weakening friction law depicted by the blue curve in Figure 2a . This law is characterized by a linear decrease in shear stress ( τ ) as a function...

... to critical prestress levels: Nucleation patch sizes are 2 km and 3 km for the M w 7.8 and 7.7 earthquakes, respectively. We demonstrate that simple friction parameters can give rise to the distinct slip characteristics of both the earthquakes, and promote dynamic and static multifault earthquake...
