Motivated by the ultimate goal of linking the binder and aggregate properties to the cracking performance of asphalt concrete, a multiscale virtual testing methodology is developed in this paper. The main components of the proposed methodology are: (a) a virtual fabrication technique that generates the microstructure of asphalt concrete specimens without the need for physical fabrication, (b) a…
The additional pile response due to the creep behavior of the soil is disadvantageous to the safety of pile. However, in the current studies for considering the creep behavior of the soft soil, the pile response induced by the long-term settlement of soil is seldom investigated. This paper mainly discusses the pile response during the excavation and operation periods considering the creep behav…
The exploitation of geothermal energy could cause additional thermal load imposed to the foundation and surrounding soils. The effects of temperature changes on the response of energy piles which can induce thermal expansion and contraction of both piles and soils need to be examined. This study investigated the behaviors of an energy pile and the surrounding soil using the model test and 2D …

The tunnel leakage in sand layer plays an important role in the evolution of the lining stresses and the ground movement. The phenomenon of internal erosion occurs when underground water leaks into the tunnel from the damaged joints or the cracks of the linings. Fines in sand are pulled off by seepage forces and transported throughout the soil matrix into the tunnel. The loss of fines due to se…
This paper reports on the first large-scale project in the U.S. for utilizing water from abandoned mines for geothermal applications. This project proved the high potential of turning water in deep abandoned mines into a renewable energy resource, which is safer, greener, and more abundant than other conventional low-enthalpy geothermal applications. In this paper, a real demonstration project …
