During the construction period of sea-crossing bridge, pile foundation and other operations are easy to cause marine water environment pollution. In order enhance green development level cross-river (sea) channel project, this paper selects Shenzhen-Zhongshan Link, a typical cross-sea traffic cluster as research object. And introduces environmental protection technologies such bored with steel ...

The flow velocity distribution in partially-filled circular pipe was investigated in this paper. The velocity profile is different from full-filled pipe flow, since the flow is driven by gravity, not by pressure. The research findings show that the position of maximum flow is below the water surface, and varies with the water depth. In the region of near tube wall, the fluid velocity is mainly ...

To investigate the treatment effect of micro-piles on uplift deformation red-bedded soft rock subgrade, an in-situ static load test slurry injected steel pipe with different length was carried out, bearing capacity and characteristics were analyzed, transfer function pile lateral friction resistance modified consideration length. A numerical simulation method considering variable shear stiffnes...

A programmed software was developed in order to numerically simulate time variation of temperature field and snow depth around a pipe-in-pile snow-melting system, using meteorological data. The system utilized underground piles as heat exchanger between underground soil and water flowing inside the piles. The water was pumped into heat dissipation pipes embedded beneath pavement surface, on whi...
