Match the following:

1. Passive pressure for cohesive soil

A. p = KγZ - 2c

2. Active pressure for cohesive soil

B. \(Z = \frac{{2c}}{{\gamma \sqrt {{K_a}} }}\)

3. Total depth of unsupported cut

C. p = KγZ + 2c

4. Depth where tensile crack

D. \(Z = \frac{{4c}}{{\gamma \sqrt {{K_a}} }}\)

Question

1. Passive pressure for cohesive soil	A. p = KγZ - 2c
2. Active pressure for cohesive soil	B. \(Z = \frac{{2c}}{{\gamma \sqrt {{K_a}} }}\)
3. Total depth of unsupported cut	C. p = KγZ + 2c
4. Depth where tensile crack	D. \(Z = \frac{{4c}}{{\gamma \sqrt {{K_a}} }}\)
