As one of the common geological disasters on seafloor, occurrence pockmarks often indicates existence submarine fluid. And formation is generally attributed to soil carried away by The research established physical model test and found: (1) pockmark formed after aeration, particle gradation changed in center area where coarse (particle size/0.25 mm) increased obviously fine size ≤0.075 decreased significantly; (2) Comparing volume with extracted siphon, it can be found that was much larger...
Siphon drainage using inclined borehole and 4 mm inner diameter pipes is an efficient stable measure for long-term landslide drainage. In order to compare alternative arrangements more efficiently, a numerical method proposed siphon process simulation. The novelty of this simulate the dynamic by series iterative seepage analyses. whole divided into many small time steps each one corresponds independent analysis. operation fully automated reading rewriting calculation document with Python...
Conventional landslide drainage methods always seem to lack a long-term and efficient capacity. Thus, it is necessary develop new method that does not have these disadvantages. In this study, new, self-starting proposed based on the results of tests were conducted with physical model. The principle involved starts automatically when level groundwater above front end permeable pipes higher than orifice. A vacuum generated in pipe after flow begins pipe, transmitted forward surrounding soil....
Drainage can effectively control landslides that are caused by the infiltration of rainfall. Laboratory model tests were conducted in this study to investigate an efficient groundwater drainage method. The identified a method self-starts and creates vacuum permeable section through siphoning. In addition, value pressure is related difference height from outlet drain section. greater height, generated However, attenuates continuously process transfer soil. It was also proved there smaller...
