RISStability of Cracking Deposit Slope Considering Parameter Deterioration Subjected to Rainfall
Publisher: ASCE
Abstract: Soil–rock mixture (SRM) shows complicated mechanical behaviors and hydraulic characteristics, which lead to challenging deposit landslides and debris problems in southwestern China. Previous studies have shown, based on ...
New Model for Predicting the Bearing Capacity of Large Strip Foundations on Soil under Combined Loading
Publisher: ASCE
Abstract: The bearing capacity of large strip foundations under combined loading is an important issue in geotechnical engineering, which is related to the design and stability analysis of foundations such as gravity dams, retaining ...
Time-Frequency Analysis of Seismic Wave Propagation across a Rock Mass Using the Discontinuous Deformation Analysis Method
Publisher: American Society of Civil Engineers
Abstract: To investigate the wave (including P-wave and S-wave) propagation across a rock mass, the seismic discontinuous deformation analysis (DDA) method is used, and a time-frequency analysis of the DDA simulation results is ...
Extension of the Discontinuous Deformation Analysis Method to Simulate Seismic Response of a Large Rock Cavern Complex
Publisher: American Society of Civil Engineers
Abstract: The discontinuous deformation analysis (DDA) method calculates large deformations and discontinuous problems using time-step solving and provides an effective tool for analyzing the seismic response of rock mass engineering. ...
Investigating the Scale Effect of Rock Mass in the Yangfanggou Hydropower Plant with the Discrete Fracture Network Engineering Approach
Publisher: ASCE
Abstract: It is well known that there is a significant difference between the strength of an intact rock sample and that of an in situ rock mass. Studying the scale effect of a rock mass is important for the estimation of the rock ...
A Dynamic Constitutive Model for Rock Materials Subjected to Medium- and Low-Strain-Rate Dynamic Cyclic Loading
Publisher: ASCE
Abstract: Rock materials are often subjected to medium- and low-strain-rate dynamic cyclic loading such as earthquake action; however, few dynamic constitutive models for rock materials under dynamic cyclic loading are available. ...
Semianalytical Analysis of Overexcavation and Critical Support Pressure for Support Design in TBM Tunneling through Squeezing Rock Condition
Publisher: ASCE
Abstract: Support damage is a typical hazard scenario associated with tunnel boring machine (TBM) drives in the squeezing rock condition. The stress release of the rock mass and the improvement of the support capacity are two effective ...
Novel Evaluation Method of 3D Joint Roughness Based on Random Field Theory
Publisher: American Society of Civil Engineers
Abstract: The roughness of a joint has a significant influence on the physical and mechanical properties of rock mass, and it is a hot and challenging research topic to determine the joint roughness quickly and accurately. In this ...
Stability Evaluation Model of Large Rectangular Foundations on Soil under Combined Loading
Publisher: ASCE
Abstract: The bearing capacity of large rectangular foundations on soil subjected to combined loading [simultaneously subjected to vertical load (V), overturning moment (M), and horizontal or lateral load (H)] is one of the central ...
