Current approaches to rockfall hazard and risk mitigation have been dominated by a model in which rockfall is treated as a global slope stability phenomenon which is mainly triggered by precipitation, freeze-thaw, or root wedging. The methods implemented by ...

<p>The immersed tunnel technique is a common used technique for river crossings in the Netherlands, but also in the United States and Japan. 80% of the immersed tunnels are built in these 3 countries. The design of the immersed tunnels differs for the different ...

<p>For many years, engineers have designed foundations, walls and culverts for highway and other geotechnical applications using allowable stress design (ASD) methods. In ASD, all uncertainties in the load and resistance are combined into a global factor of ...

This report develops and calibrates procedures and modifies the AASHTO LRFD Bridge Design Specifications, Section 10, Foundations for the Strength Limit State Design of Shallow Foundations. The material in this report will be of immediate interest to bridge ...

<p>While site effects are accounted for in most modern U.S. seismic design codes for building structures, there exist no standardized procedures for the computationally efficient integration of nonlinear ground response analyses in broadband ground motion ...

<p>Load and resistance factor design (LRFD) (often called limit states design (LSD)) has been mandated in the AASHTO Bridge Design Specifications and will be adopted in future editions of Canadian Highway Bridge Design Code for all transportation-related structures ...

We first review, in five sections, the external perturbations and their associated processes which can lead to landslide failure: i) increase of slope angle, ii) increase of load applied to the slope, iii) rise of groundwater level and pore pressure, iv) frost ...

This thesis deals with the treatment of urban landfill leachate by partial nitritation SBR (Sequencing Batch Reactor) technology as a preparative step for an anammox reactor.

Evidence indicates that the vertical component of ground motion is more significant than previously thought, especially for near fault events. However, many design codes do not reflect the importance of the vertical component of ground motion. Therefore, ...

<p>This thesis is intended as a detailed analysis of a candidate dynamic fault weakening mechanism called thermal pressurization of porefluid, based on the theory of thermoporoelasticity and on the latest geological, laboratory, and theoretical field results.</p ...
