Foundation Deep Foundation Llpile Pdf Pdf Deep Foundation Deep foundations are employed when the soil strata immediately beneath the structure are not capable of supporting the load with tolerable settlement or adequate safety against shear failure. piles are relatively long, slender members that are driven into the ground or cast in situ. Accordingly, this paper mainly going to focus on classifications of deep foundations, its mechanisms, the evaluation methods of axial load capacity of a deep foundation and the steps and the methods of designing a deep foundation.
Deep Foundation Final Rev1 Pdf Deep Foundation Soil Mechanics 1) deep foundations such as piles, piers and caissons are used when the load of the structure is heavy, the soil has low bearing capacity, or there are issues with subsurface water or soil stability. 2) piles can be classified based on their function, material, and method of construction. •deep foundation timber concrete steel •carry loads to large depths below gl. pile foundation 11 13 2018 3. pile foundation 11 13 2018 4. Deep foundations can usually take larger loads than shallow foundations that occupy the same area of the ground surface. deep foundations can reach deeper competent layers of bearing soil or rock, whereas shallow foundations cannot. deep foundations can also take large uplift and lateral loads, whereas shallow foundations usually cannot. Deep foundation performance must be considered for deep foundations in seismic areas. • deep foundations are often used as fender systems to protect bridge piers from vessel impact, figure 9 1(i).

Types of deep foundations 1. driven piles materials wood, precast concrete, steel sections octagons, solid circles, rings, h sections limitations vibrations due to driving? head room? deep foundations usually l b > 5 l = pile length, b = dia. or breadth of pile. Piles are common foundation tools for transferring superstructure through water and or soft soil deposits. the loads may be distributed through the soils (friction piles) or transferred to firm, underlying soil or rock strata (end bearing piles). most piles function as a combination of the two. This chapter provides general guidance in the design and analysis of deep foundations used to support highway structures. deep foundations consist of driven piles, drilled shafts or piers, drilled piles, auger cast in place (continuous flight auger, cfa) piles, micro piles and pile or drilled shaft supported footings.
