水工07级水工建筑物考试答案(国外英文资料) 2009-2010 school year second semester the hydraulic architecture Ⅰ final exam (class 07 hydraulic professional) Class student id name Results. One, not a problem: (square root, wrong number two, 20 points for each question) 1. The basic section of gravity dam is refers to the weight of the dam and the static water pressure and uplift pressure three main loads, satisfy the stability requirement, and make the smallest triangle section of quantities. (x) The backfill grouting object is the space between the lining and the surrounding rock, and the consolidation grouting is made for the whole section of the tunnel. (fx) The smaller the center Angle of the arch dam, the more favorable the stability of the dams shoulder, the worse the stress. (x) At the end of the gate, the platform is small and can weaken the wave water jump, but it has a slight effect on the discharge capacity. (fx) 5. The dam of earth-rockfill dam slope stability calculation with severe substitution method considering penetration effect, the downstream water level under the soil, sliding moment in the saturated severe, when calculating anti-sliding moment with heavy. (x) The stress control standard is controlled by vertical and positive stress in the calculation section. (x) The resistance coefficient of the seepage segment of the water gate on the soil is only related to the geometry of the seepage section. (fx) The main bar should be checked for longitudinal bending stability. (fx) If the effect of the arch effect is obvious, the wall of the clay core of the earth rock may produce a horizontal crack. (fx) When the tunnel hole is forced to make a turn in the layout of the plane, it is advisable to put the work gate above the curve. (x) Two, one choice question (two points per problem, 20 points) The stress (A) of the longitudinal seam is applied to the heel of the dam when the upstream dam is set in reverse. A. advantage b. disadvantage c. not d. no The main water brake on eart
