earthquakes could have catastrophic impacts on tunnels and buried structures. liquefaction phenomenon is one of the most destructive effects of earthquakes. liquefaction results in decreasing effective stress and this consequently leads to decreases in shear strength of the soil. as a result, large deformation in both soil and buried structure occurs. moreover, liquefaction causes soil boiling,...

Fault modeling is a very important step in making an accurate and reliable 3D geological model. Typical existing methods demand enough fault data to be able to construct complex fault models, however, it is well known that the available fault data are generally sparse and undersampled. In this paper, we propose a workflow of fault modeling, which can integrate multi-source data to construct fau...

We summarize studies of earthquake fault models that give rise to slip complexities like those in natural earthquakes. For models of smooth faults between elastically deformable continua, it is critical that the friction laws involve a characteristic distance for slip weakening or evolution of surface state. That results in a finite nucleation size, or coherent slip patch size, h*. Models of sm...

A formal analysis of the fault diagnosis capabilities of various FSM-based test sequence selection methods has been carried out’. It is shown’ that the Wp-method’ has the best faultresolution capability among all the known test sequence selection methods based on the FSM model when the implementation has at most one faulty transition. In this paper, we present a test sequence selection method w...

The goal of this work is to present some theoretical results which can be used for increasing fault sensitivity of a detection scheme, without sacrificing robustness. Robustness against modeling uncertainties and fault sensitivity are two contradicting demands, and typically, one is achieved at the expense of the other. The main reason for this trade-off is the use of a worst case scenario boun...

Abstract The magnitude of earthquakes on continental normal faults rarely exceeds 7.0 Mw. However, because their vicinity to large population centers they can be highly destructive. Long recurrence time, relatively small deformations, and limited observations hinder our understanding the deformation patterns mechanisms controlling events. Here, this problem is addressed with 2D thermomechanical...

classical soil mechanics involves the study of fully saturated soils. however, many problems encountered in geotechnical engineering practice involve unsaturated soil, in which behavior is significantly different from classical saturated soil. negative pore pressure and capillary forces develop a virtual cohesion between the grains of semi saturated soils. this kind of cohesion is dependent on ...
