The marine concrete engineering in cold area has been stayed in the harsh marine environment for a long time, lower the effective service life, which depends largely on the seawater freeze-thaw and corrosion interaction.
In the Marine concrete engineering, although incorporating slag and fly ash improved corrosion resistance to salt water, but the ability to resist to freeze-thaw cycle is somewhat weakened, the author in the years of experimental study on concrete with high resistance to water freeze-thaw in cold regions, found that high air content is very effective.

Mechanisms Of Rock Slope Failure In Selected Quarries In Oyo State, Nigeria J.M Akande 1, a and M.A Idris 2, b (1, 2) Department of Mining Engineering Federal University of Technology, Akure, Ondo State.
Introduction The stability of natural and man-made slopes is of great concern to both mining and civil engineers for numerous types of site uses and objectives.
Mechanism of failure of a particular slope is governed by the engineering geology conditions of the rock mass and is almost always unique to a particular site.

Deformation Pattern of Foundation Pit Excavation beside Silt Soil Railway Subgrade Fangding He1, a,Guangjun Guo2,b,Yanan Zang3,c 1Hydraulic Research Institute of Shandong Province, Jinan, 250014, China 2Department of Water Resources of Shandong Province, Jinan, 250014, China 3School of Civil Engineering, Shandong University, Jinan, 250061, China a6974554@126.com, b6974470@126.com, czang_yanan@163.com Keywords: Silt soil area; Subgrade overload; Train's vibrating load; Foundation pit seepage; deformation pattern Abstract: Foundation pit excavation beside silt soil railway subgrade in the water net plain district is influenced by overload of backfilled roadbed, train's vibrating load and high groundwater level, so foundation pit instability occurs easily.
Therefore, this paper based on 18# of the main Interchange bridge pile engineering in the Qingyin Expressway Yucheng South, considered the seepage of foundation pit, the train dynamic load and other factors, numerical simulating parameters such as different excavation depth, different distance from the subgrade, revealed the deformation mechanism and the main influencing factor of foundation pit, put forward foundation pit deformation law can provide theoretical reference for similar engineering anchor-plateretaining designed.
