## design a conventional drilled and grouted soil nail wall to retain a long, vertical excavation in a silty sand.

A conventional drilled and grouted soil nail wall will be designed to

retain a long, vertical excavation in a silty sand. The soil properties and

the design excavation depth are shown in Figure 7.60. The following initial

parameters are also given:

Pullout factor of safety, FSp = 2.0

Global factor of safety, FSG = 1.35

Nail horizontal spacing, SH = 1.5 m

Nail vertical spacing, SV = 1.5 m

Nail inclination = 15 degrees

Drillhole diameter, DDH = 10 cm

Ultimate pullout resistance, qu = 120 kN∕m²

Determine:

(1) The preliminary nail length and maximum design nail tensile force

to satisfy the global stability.

(2) The factor of safety against sliding.

(3) The factor of safety against heaving of the foundation soil.
