Soft Foundation Strengthening Effect and Structural Optimization of a New Cement Fly-ash and Gravel Pile-slab Structure
Reducing the settlements of soft foundation effectively is a critical problem of high-speed railway construction in China. The new CFG pile-slab structure composite foundation is a ground treatment technique which is applied on CFG pile foundation and pile-slab structure composite foundation. Based on the experience of constructing Beijing-Shanghai high-speed railway in China, the settlement-co...
متن کاملSLAB Benchmarks
Abstraction and slicing are both techniques for reducing the size of the state space to be inspected during verification. In the paper [1], we present a new model checking procedure for infinite-state concurrent systems that interleaves automatic abstraction refinement, which splits states according to new predicates obtained by Craig interpolation, with slicing, which removes irrelevant states...
متن کاملSlab pull, slab weakening, and their relation to deep intra-slab seismicity
[1] Subduction zone seismicity is highly variable. Great earthquakes occur at few subduction zones around the world, with significant variation in size and frequency of deep events. Interactions between overriding and subducting plates and slab pull strength for individual plates provide a framework for understanding these variations. Previous work suggests an inverse correlation between great ...
متن کاملThe wet Nicaraguan slab
[1] Nicaraguan volcanoes show globally high concentrations of geochemical tracers from dehydration of subducting crust, which may reflect a slab with unusually high amounts of H2O. To test this possibility, we measure seismic velocities at the top of the subducted plate and compare them with predictions for hydrated mafic rocks. Regional seismic P waves for intraslab events at 100–150 km depth ...
متن کاملMulti-Slab SPACE
Introduction Single Slab 3D turbo spin echo sequence with variable refocusing flip angles (aka SPACE) [1, 2, and 3] has been optimized for PDw, T2w and T1w contrast imaging. In order to obtain 3D high resolution and reduce the acquisition time to the clinical acceptable range, the TR has to be shortened dramatically compared to conventional TSE imaging. Moreover, a relative long echo train has ...
