Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….
Determine the preliminary nail length and maximum design nail tensile force to satisfy the global stability.
A hollow bar soil nail wall is used as a temporary soil retention struc-
ture. The retained soil and its properties are shown in Figure 7.61. The
following design parameters are also selected for this project:
Pullout factor of safety, FSp = 2.0
Global factor of safety, FSG = 1.4
Nail horizontal spacing, SH = 1.5 m
Nail vertical spacing, SV = 1.5 m
Nail inclination = 15 degrees
Drillhole diameter, DDH = 200 mm
Ultimate pullout resistance, qu = 120 kN∕m²
(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 the heaving of the foundation soil.
