The ties for the anchored bulkhead shown in Figure 9-16 are located four feet from the top of the
sheetpiling and are spaced at fifteen feet centers. The end of the tie is secured to two anchor piles raked as indicated. The active earth pressure may be assumed equivalent to a fluid pressure of 30 pounds per square foot per foot and passive pressure may be assumed equivalent to a fluid pressure of 400 pounds per square foot per foot.
For the depth of penetration indicated, calculate the value of the total active pressure on the back of the wall, the value of the total passive pressure on the front of the wall, and the moment of all forces about the tie point. Determine the forces in the tie, the maximum shear and the maximum moment in the wall, and the forces in the compression and tension anchor piles.

The fill behind the retaining wall in Figure 9-17 has a unit weight of 110 pounds per cubic foot with an equivalent fluid pressure of 30 pounds per square foot per foot. Passive earth pressure may be assumed equivalent to a fluid pressure of 300 pounds per square foot per foot and the coefficient of friction at the underside of the base is 0.4. All concrete has a compressive strength of 3000 pounds per square inch and reinforcement consists of Grade 60 deformed bars. Neglecting the effects of the shear key, determine the factor of safety against overturning and the bearing pressure distribution under the base. Using factored loading, determine the reinforcement, calculate the minimum depth of the shear key to provide a factor of friction of1.5 against sliding.
The mass concrete gravity dam shown in Figure 9-18 is 20 feet high. Determine the minimum base width if no tensile stresses are allowed in the concrete and the water level is at the top of the dam wall.
Details of a counterfort retaining wall are shown in Figure 9-19. The fill behind the wall has an equivalent fluid pressure of 40 pounds per square inch and reinforcement consists of Grade 60 determined bars. Determine the horizontal reinforcement required at the base of the stem in the front and earth faces, the reinforcement required at the base of the counterforts.
Determine the required penetration of the sheetpile retaining wall shown in Figure 9-20 if active earth pressure may be assumed equivalent to a fluid pressure of 35 pounds per square foot per foot and passive pressure may be assumed equivalent to a fluid pressure of 450 pounds per square foot per foot. Calculate the force in the tie and the location and magnitude of the maximum shear and the maximum moment in the shestpiling.
翻译：由于对土木工程方面没有研究，所以很多专业术语是靠GOOLE差找和个人猜测，可能会不尽准确，甚至有所错误，但是本着学习的态度，我还是很认真地翻译了。我猜测，这可能是某本英文版建筑教材后面的习题吧？所以我用了习题的语气做的翻译。望对你有所帮助。
