Cost-Effectiveness Evaluation of Pavement Maintenance Treatments by OPTime
The cost-effectiveness of different maintenance treatments including micro surfacing, HMA overlay and mill & fill were evaluated by using OPTime. The treatment effectiveness was calculated as the difference in computed areas associated with the post-treatment performance indicator curve and the do-nothing curve. It was found that mill & fill had the highest unit costs, followed by HMA overlay a…
Tuuneling-Inducced Ground Response: Simulating Synchronous Grouting in Shield…
Synchronous grouting is one key procedure to backfill the construction gap and control the ground subsidence. The grouting prsessure and grout properties are key construction factors that dominate the consequence of synhronous grouting. To investigate the effect of these factors, a novel framwork to simulate the process of synchronous grouting is proposed in this paper. LOKASI: Ruang Koleksi…
The Behavior Analysis of a Cofferdam Constructed by Double Sheet Pile Wall Ab…
This paper presents an investigation on the behavior of a cofferdam structure constructed by double sheet pile walls above the muck, which is used to construct the inner foundation for an immersed tube tunnel project in GuangZhou China. A detailed three-dimensional FEM model is formulated to simulate the whole prosesse, including the construction of the cofferdam and the excavaction of the inne…
