原文： Design the leader Is it draw materials on real project letting camp aqueducting to design originally , let camp aqueduct land muddy irrigated area leap building , Iraq of river of east one trunk canal. The muddy irrigated area of land is one of bigger irrigated areas of Henan Province, the irrigated area is in half a mountain areas and mound mountain range areas, crosses over six counties of three areas in Luoyang , Kaifeng , Zhengzhou, the irrigated area of irrigated area is 57.61 hectares. The whole irrigated area is done the composition of three trunk canals by two total trunk canal and the east one , the east, the west, total length 290.5m, 1134 .32 aqueducts buildings, total length 9.8Km. East one trunk canal plan 3.841 of irrigated area, in the east one irrigated area more for hills arid area, the hillock depression is alternate in the district, the ground is covered for the red and brown clay and loess, hydrogeology is relatively bad, lack the underground source of water . Let camp aqueduct plan axis long 748.1m, this section for being getting mauve, getting reddish brown conglomerate insert sand quality clay, the conglomerate composition is quartz sandstone , quartzite ,etc., the surface is weathered seriously, protruding and concave and not smooth, the naked eye can see the corrosion, the diameter comes in different sizes, there is phenomenon of infiltrating in the hole. Let camp aqueduct larger aqueduct at the east one trunk canal , so to is it concern whole east one trunk canal of planning irrigated areas or not to build up aqueduct this, irrigated area of planning of the muddy irrigated area of the even whole land. Originally designing the rank of the building according to tertiary consideration, it is 80 to design the earthquake intensity. The task originally designed has two items mainly, let geology topographical terms , camp of section according to east one trunk canal , draft two different kinds of leap building pattern of river for the first
