A certain clayey soil contains 0.30 percent sulfates. Would you anticipate a problem with con-crete foundations in this soil? Are any preventive measures necessary? Explain.
Describe the factors affecting soil consolidation?
You are planning to build a three story above ground building with a basement parking garage below ground. The bottom of your slab/foundation will be 17 ft below existing grade. You plan to keep the ground water level in the excavation 3.0 ft below the bottom of the foundation for approximately 3 months. The water table is 11 ft below existing grade. The soil is uniform medium sand down to a depth of approximately 50 ft. The soil below 50 ft is an impervious clay. Your excavation will be 320 ft x 150 ft. You have determined that a 4 ft wide x 3 ft deep sump around the perimeter of your excavation will provide adequate dewatering capacity. Based on test wells on site, you determined that the medium sand has a k value of .058 ft/min and that the D factor is 50 ft.
a. Label D, H, and ht on the given diagramb. Calculate the flow rate, q c. Calculate the total volume of water that will need to be pumped in gallons per minute (GPM)

Explain.arrow_forwardA concentrated load of 460 tons is applied to the ground surface. You are a little, helpless ant located 13 feet below grade and 9 feet off center of this concentrated load. The soil has a unit weight of 128 lb/ft3 and the water table is located at a depth of 6 feet below grade (thank goodness you have your scuba gear!).

These soils are fairly uniform and probably have good engineering properties. The building will have one 12 ft deep basement and will probably be supported on either a mat foundation located 5 ft below the bottom of the basement, or a deep foundation extending about 60 ft below the bottom of the basement. The groundwater table is about 30 ft below the ground surface and bedrock is several hundred feet below the ground surface. There are no accessibility problems at this site. i) How many exploratory borings will be required, and to what depth should they be drilled? ii) What type of drilling equipment would you recommend for this project?arrow_forward
- How and why the concept of principal stresses is used to measure the strength of soil?arrow_forwardA five-story steel-frame office building with a 100 ft x200 ft footprint is to be built on a site underlain by clays and silts. These soils are fairly uniform and probably have fair engineering properties. The building will have one 20-ft deep basement and will probably be supported on either a mat foundation located 5 ft below the bottom of the basement, or a deep foundation extending about 60 ft below the bottom of the basement. The groundwater table is believed to be about 15 ft below the ground surface and bedrock is about 85 t below the ground surface. There are accessibility problems at this site with trees and steep terrain. (a) How many exploratory borings will be required as per NYC Code, and to what depths should they be drilled (for both shallow and deep foundation sehemes?)
