GEO-ETKA, INC. Job No: F-12136-24 3 Laboratory Testing (cont’d) The method of performing these tests is to saturate the sample, to extrude the sample into the test apparatus, to apply the normal load, and than to allow sufficient time to elapse to dissipate any excess hydrostatic pressure. The sample is then subjected to a strain-controlled single plane shear test. The method of applying the normal and shearing load is such as to allow the sample to change in volume without producing an associated change in the normal stress. The shearing stress is measured at a constant rate of strain of approximately 0.05 inches per minute. Selected samples of soil were tested at confining pressures similar to those of the materials in-situ. Additional specimens from the same samples were also tested at increased normal pressures in order to determine the increase in shear strengths associated with increased inter-granular pressure. The test results are plotted graphically on Plate “C”. The resulting values are as follows: CONCLUSIONS Suitability of the Project The site is suitable for its intended use i.e. a 2 ADU units. In designing the proposed structure, the criteria given in the design section should be adhered to. a. The construction of this project will not affect the stability of the surrounding structures, such as walls, electric poles, etc., provided all precautions needed are followed. b. The latest applicable unified building code is to be followed as required. c. This report is subject to approval by the governing agencies. Strength Characteristics The load bearing soils possess strength parameters adequate to support the proposed construction. Angle of Internal Cohesion Soil Type Friction (degrees) (p.s.f.)
