Question

For 450 mm side square section concrete pile 15 m long is driven in a deep deposite of uniform clay.
The laboratory unconfined compression test on undisturbed sample indicates an avg. value of (Q.)
unconfined compresive Strength = 75 kN/m2. Calculate the ultimate load capacity of pile. Take
a = 0.8. Ysat = 18 kN/m?, Y = 10 kN/m3​

Answer 1

Explanation:

=0 analysis: Suppose W is the weight of the soil of wedge ABDA, is the unit arm, c is the unit cohesion, l is the length of the arc of the slip surface. . The factor of safety is given by This factor of safety is determined for each trial slip surface, and the one having the minimum factor of safety is termed as the critical slip surface.
