Instability of submarine slopes in Zhoushan Islands is widespread. Frequent landslides pose a great threat to offshore facilities such as optical cables, reclamation projects, ports and docks. In this paper, self-developed in-situ observation system used observe the deformation on southwest side Zhujiajian Island for 75 days. The results show that characteristics sediments at different depths s...

Wave scattering over a sinusoidal bottom in the presence of vertically sheared current is investigated experimentally and compared with modified-mild slope model taking into account linear vertical shear. Waves were generated flume without or an opposing propagated patch 10 bars before dissipating on beach. The shear was controlled using perforated screen. Doppler shift resonant Bragg frequency...

To analyze the excavation stability and reasonable reinforcement measures of cutting slope with a goaf collapsed roadway mining face, finite element software Midas GTS NX was used to model change in coefficient under different ratios. Combined scope project land, it is proposed that ratio grades 1–3 (close top cut) 1:1.5, while 4–6 bottom 1:1, excavate slope. During process, plastic zone after ...

Lipid biomarkers and C fractionation patterns were used to understand the dynamics of carbon cycling during microbial metabolisms in different environments of travertine precipitation (called facies) at Spring AT-1 on Angel Terrace in the Mammoth Hot Springs complex of Yellowstone National Park, USA. Microbial mats that encrust travertine deposits were collected for analyses of lipid biomarkers...

To investigate the toppling displacement evolution characteristics of anti-dip rock slopes, Xiaodongcao-Zhengjiadagou bank slope is taken as an engineering case, and firstly, geological geometric distribution are obtained by superimposing lithology, slope, elevation raster layers through ArcGIS, partition with largest area Lower Triassic Daye Formation, bottom elevation, medium slope; based on ...
