- Refer to Problem 8.4. Using the flow net drawn, calculate the hydraulic uplift force at the base of the hydraulic structure per meter length ( measured along the axis of the structure).A concrete gravity dam with a trapezoidal section is holding water as shown in the figure. A distance of 15 meters from the toe, a drain is located. The drain has a pressure due to uplift of zero and increasing uniformly to full hydrostatic at the heel. Upstream face 1H:5V, while downstream face is inclined 1H:2V. Which of the ff nearly gives the maximum foundation pressure on the base of the dam in kilopascal ? Assume 23.54 kN/m3 for the unit weight of concrete. a. 3114 b. 1095 c. 4115 d. 964 e. 680A masonry dam of trapezoidal cross section, withone face vertical has a thickness of 60 cm at the top,3.70 m at the base, and has a height of 7.40 m.What is the depth of water on the vertical face ifthe resultant intersects the base at the downstreamedge of the middle third? Assume that the upliftpressure varies uniformly from full hydrostatic atthe heel to zero at the toe. Follow the steps: Step 1. Solve for all the forces. Step 2. Solve for Rx and Ry. Step 3. Solve for RM and OM. Step 4. Solve for x, where we will get the value of h or the depth of water. Note: The answer must be near or exactly 5.83m.

A rectangular dam with base equivalent to 2.5-meters and height equivalent to 6-meters holds water with an upstream height of 4.5-meters. Compute for the factor of safety against sliding and overturning. Unit weight of concrete is 23.54 kN/cu.m. Consider 1 meter length strip. Disregard hydrostatic uplift pressure. The coefficient between the dam and the foundation is 0.4.A concrete gravity dam has the following data: Maximum water level = 300.00 m Bed level = 220.00 m R.L top of dam = 304.00 m %3D The d/s slope of 0.67:1 starts at RL of 295.00 m U/s face is vertical. Center line of the drainage gallery = 8.0 m from u/s face. Consider only weight of dam, water pressure and uplift pressure. Calculate only the normal stresses at the toe and heel of the dam, assuming 100% uplift pressure at the h eel and 50% at the gallery and zero at the toe.
