Textbook Problem

Following are the results of a standard penetration test in fine dry sand.

For the sand deposit, assume the mean grain size, *D*_{50}, to be 1 mm and the unit weight of sand to be 18.5 kN/m^{3}. Estimate the variation of relative density with depth using the correlation developed by Cubrinovski and Ishihara [Eq. (17.18)]. Assume *p _{a}* ≈ 100 kN/m

To determine

Find the variation of relative density with depth using the correlation developed by Cubrinovski and Ishihara.

Explanation

Given information:

Show the depth and number of blows shown in table:

Depth,(m) | |

0.5 | 6 |

2.0 | 9 |

3.5 | 12 |

5.0 | 14 |

6.5 | 17 |

Assume the average unit weight

The mean grain size

The atmospheric pressure is

Calculation:

Calculate the overburden pressure

Here, *z* is depth.

Substitute

Show the expression to find correlation of relative density by using Cubrinovski and Ishihara.

Substitute

Thus, the variation of relative density at the depth

Calculate the overburden pressure

Substitute

Find correlation of relative density by using Cubrinovski and Ishihara at the depth

Substitute

Thus, the variation of relative density at the depth

Calculate the overburden pressure
