Re: Job No. 74-79
Proposed Two Story Residence 1715 Butters Drive Carlsbad, California
Subject: Bearing Capacity
Dear Mr. Stone:
Enclosed are the results of our observations and tests
as you requested for the above referenced project to determine
the bearing capacity of the proposed foundation system and any
obvious geologic problems on the site.
It is understood the proposed residence will be a hexagonal
shaped wood frame house. The foundation will use continuous wall
footings with isolated footings in the interior. The footings
were designed for 2000 psf in bearing.
On 26 June 1974 a representative of this laboratory dug two
test holes in the house area. The holes revealed the site is
located on firm nonexpansive native soil. The soil profile is
described as 6 inches of loose topsoil which grades to brown
weakly cemented sandstone. A field density test was taken at
the proposed footing depth and the soil sample returned to the
laboratory for the bearing capacity determination.
The soil sample was remolded to the inplace conditions of
moisture and density in three 1 inch high 23 inch diameter brass
.r molds. The molds were loaded urith normal loads of .5, 1.0, and
1.5 K.S.F. respectively and sheared to failure in the undrained
condition. The values of internal friction and apparent cohesion
derived from this test were used in the Terzaghi Formula in
accordance with the procedure outlined in Ref. 1, page 170, to
compute the allowable bearing capacity. The results follour:
DIRECT SHEAR TEST
Unit Density Angle of Internal Apparent Allowable Bearing
Friction Cohesion Capacity
0 (psf) (psf) (PCf)
117 30 580 2890
Terzaghi Formula:
Bearing Capacity = 2/3cNfc + dDfN*q + &dBN;
Assumptions:
Depth of Footings, Df = 1.5
Width of Continuous Footing, B = 1.5
Ntq, Nt = dimensionless parameters found,from NtC’ t
Fig. 75, Ref. 1.
Factor of Safety = 3.
Conclusion:
1 - Based on our tests and field observations it is our
opinion that the existing foundation system is adequate to
support the proposed house.
2 - There was no expansive soil, existing fill, or other
obvious geologic hazards observed.
