There are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of China lands which are facing serious problem of desertification. Theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofNortheast China, North central china and most of northwest china. Biological methods are theultimate way for drift sand stabilization and a fu...

Drifting snow, the flow of dispersed snow particles near ground level under action wind, is a major form damage. When drifting occurs on railways, highways, and other transportation lines, it seriously affects their operational safety results in disasters. disasters frequently occur high latitudes northwest China. At present, most scholars are committed to studying prevention control measures b...

A clothoid has the property that its curvature varies linearly with arclength. This is a useful feature for the path of a vehicle whose turning radius is controlled as a linear function of the distance travelled. Highways, railways and the paths of car-like robots may be composed of straight line segments, clothoid segments and circular arcs. Control polylines are used in computer aided design ...

In this article, flood floods affecting automobile roads and natural disaster relapse on maps using geoinformation systems. The consists of forecasting the arrival. impact highways was considered from studied factors. Flood (Flood current) - a stagnant mud or rock stream consisting mixture water fragments that suddenly appear in basins small mountaineers. How to increase productivity, movement,...

Abstract In order to ensure energy security, China should make full use of existing resources, such as the open space on highways, highways and railways, roofs industrial mining areas, towns villages, large-scale clustering deserts, gobi, wastelands grasslands vigorously develop new photovoltaic power wind power. At same time, construction pumping solar thermal storage stations mountains variou...

Optimal whole life design for railways, highways, runways, and metro lines requires an accurate assessment of how their underlying geomaterials respond to large numbers wheel-loading cycles. This paper presents experimental study on a natural UK stiff clay with cyclic triaxial (CT) hollow cylinder apparatus (CHCA) that imposed K0 stress conditions. The focus is Gault clay, high overconsolidatio...

Purpose. The purpose of the study is to assess state vehicle traffic safety at intersection highways and railways same level, as well subsequent development measures improve road railroad crossings. Assessing degree railway crossings one main tasks both operation service transport services. Therefore, it advisable implement a system for assessing level crossings, which necessary identify danger...
