Experimental Study On Soil Pressure Of Stiff Rectangle Channel-Buried Culvert

The culvert is widely used in water conservancy, highway, railway, etc. It can be mainly divided into two parts: channel-buried culvert and positive buried culvert. However, because lack of thereasonable earth pressure theory for design of these culverts, some of them fail in theperiod of construction or after completion of work for using smaller size of structure, insome case over big size of culvert structure are designed to bear the uncertain pressureson the culverts and led to more cost. Based on the occasion above, the earth pressuretheory and the method of load reduction are studied through model test and numericsimulation to find a reasonable earth pressure theory for the culverts beneath the highfill. The fruits of research in the thesis as follow: (1) A series of testings about stiff rounded culvert in the house have been carried on based on the stiff foundation and sand soil.Slope of trough wall;the condition of positive buried culvert. the result involves the earth pressure on the top of culvert , the lateral earth pressure and the...
