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…
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…
Calculating thermal stresses of asphalt pavement in environmental conditions
Asphalt mixtures are a type of thermorheologically simple materials, so the study work on thermal stresses in asphalt pavements should be carried out beyond the scope of thermalviscoelasticity theory. Taking thermalviscoelasticity theory as a guide, the stress relaxation test of asphalt mixtures is studied in different temperature environment. The test data are analyzed and the interrelated mod…
Numerical simulation for interaction between tyre and steel deck surfacing
The structure of steel deck surfacing is different from that of the common asphalt pavement on highway. The interaction between tyre and surfacing, which took geometric nonlinearity, material nonlinearity and non-linear interaction into consideration, was analyzed in this paper. A strain energy density function called Rivilin model was used to simulate the mechanical performance of tyre. The La…
Dynamic Responses Model of Asphalt Pavement under Complex Vehicle Loads
The overweight vehicles create complex moving vehicle loads described as dynamic, three-dimension non-uniformly distributed contact stresses between tire and pavement surface. But existing calculation models and methods for structure mechanics of pavement cannot analyze the mechanical response of pavement under complex vehicle loads. Based on the theory of three-dimension elastic dynamics, the …
