Pre-Grouting Treatment and Flow Numerical Simulation for the Landslide Area of Dalian Metro

Abstract

The study discusses the simulation analysis based on the modflow software. Generalize body site, zone and boundary conditions of simulation, make a finite element model based on the geology of the Collapse of Lot 110 , Dalian Metro. Determine the accuracy of the simulation results based on the comparison between the test and the field measurement data. And then predict the flow of groundwater and the penetration. Base on the software simulation of the surface displacement and field observation wells pumping records, to calculate the water surface elevation and the elevation, the general trend of measuring is same and the values are ​​consistent. Prove the necessity of the injection that is used in the accident.

Numerical Simulation Study on Development of Geothermal Resource in the Borehole Wall Surrounding Temperature Field

“…Geothermal resource [1][2][3][4] is a very clean energy, whose exploration and development has a history of nearly a century, especially in Iceland, Italy, New Zealand, etc. But on a global scale, it has been used as a kind of new energy to carry on the exploration and development only in recent decades.…”

The Safety Transportation of Bulk Solid Cargoes

“…When loading bulk cargo in the tween deck [4], the hatch cover should be closed if the loading data is clearly shown that opening hatch cover will result the overloading of the ship' bottom. The goods should be properly trimmed.…”
