1 (PREVIEW) SP 36 (Part 2) : 1988 COMPENDIUM OF INDIAN STANDARDS ON SOIL ENGINEERING PART 2 IS 1893 : 1979 (Reaffirmed 1987) CODE OF PRACTICE FOR SUBSURFACE INVESTIGATION FOR FOUNDATIONS 1.1 This code deals mainly with subsurface investigations for foundations of multi-storeyed buildings to determine : a) sequence and extent of each soil and rock stratum in the region likely to be affected by the proposed work b) nature of each stratum and engineering properties of soil and rock which may affect design, and mode of construction of proposed structures and their foundations; c) location of ground water, and possible corrosive effects of soil and water on foundation materials Aspects relating to procuring representative samples of the soils and rocks, obtaining general information on geology, seismicity of the area, surface drainage, etc, and subsurface investigations for availability of construction materials are also mentioned briefly Most of the provisions of this code are also applicable to subsurface investigation of underground and overhead water tanks, swimming pools and (abutments of) bridges, roads and air fields.

2 IS 2720 (Part 33) : 1971 (Reaffirmed 1978) METHODS OF TEST FOR SOILS PART 33 DETERMINATION OF THE DENSITY IN-PLACE BY THE RING AND WATER REPLACEMENT METHOD 1,l This standard (Part 33) covers the method for determining the in-place density of a coarse grained soil including gravels, cobbles, boulders and rock by the water replacement method using a circular ring on the surface and a plastics film to retain the watel (see Notes 1 and 2). NOTE 1 If desired, successive density tests may be performed as the hole is progressively deepened to determine the variation of density with depth, for example, when placing and compacting material in relatively thick layers. NOTE 2 A field grading of the excavated soil may, if desired, be done while the test hole is being excavated The field dry density is determined either for the total material or for the material smaller than a specified or given size.

3 IS 1888 : 1982 (Reaffirmed 1988) METHOD OF LOAD TEST ON SOILS 1.1 This standard lays down the method for conducting load test for estimation of bearing capacity of soils and its settlement.

4 IS 9214 : 1979 (Reaffirmed 1987) METHOD OF DETERMINATION OF MODULUS OF SUBGRADE REACTION (K-VALUE) OF SOILS IN FIELD 1.1 This standard deals with the method for. The determination of modulus of subgrade reaction of the soil in-place (generally known as K-value of the subgrade) for evaluation of strength of subgrade for roads, runway pavements and raft foundations.

5 IS 9640 : 1980 (Reaffirmed 1987) SPECIFICATION FOR SPLIT SPOON SAMPLER 1.1 This standard covers the requirements of split spoon sampler used for conducting in-situ standard penetration test in soils.

6 IS : 1983 SPECIFICATION FOR EQUIPMENT FOR SUBSURFACE SOUNDING OF SOILS 1.1 This standard covers the specification of the equipment used for determining the subsurface sounding property of soil using cone with the dynamic method.

7 IS 4968 (Part 3) : 1976 (Reaffirmed 1987) METHOD FOR SUBSURFACE SOUNDING FOR SOILS PART 3 STATIC CONE PENETRATION TEST 1.1 This standard (Part 3) covers the procedure for the determination of the cone resistance and friction resistance of soil at various depths below ground surface by the static cone method This standard gives the procedure for the test only and certain essential details of the equipment but does not include complete design of the equipment.

8 IS 4434 : 1978 (Reaffirmed 1987) CODE OF PRACTICE FOR IN-SITU VANE SHEAR TEST FOR SOILS 1.1 This standard covers the procedure of conducting in-situ vane shear test in saturated cohesive deposits for determining their inplace shearing resistance. Two methods of the test, namely, testing from bottom of a bore-hole and by direct penetration from ground surface, are covered.

9 IS : 1981 (Reaffirmed 1987) CODE OF PRACTICE FOR SITE INVESTIGATIONS FOR FOUNDATION IN GRAVEL-BOULDER DEPOSIT 1.1 This code deals with the subsurface investigation in relation to design of foundations for single and multistoreyed buildings, overhead water tanks, piers and abutments of bridges in boulder-gravel deposits.

10 IS 2720 (Part 31) : 1969 METHODS OF TEST FOR SOILS PART 31 FIELD DETERMINATION OF CALIFORNIA BEARING RATIO 1.1 This standard (Part 31) covers the method for the determination of the bearing ratio (generally known as the California bearing ratio) of soils in-place for the evaluation of strengths of sub-grade and bases for roads and runway pavements.

11 IS : : 1983 SPECIFICATION FOR EARTH AUGERS (SPIRAL TYPE) 1.1 This standard covers dimensional and general requirements for earth augers (spiral type), used in piling, soil boring and sampling works.

12 IS : 1725 : 1982 (Reaffirmed 1988) SPECIFICATION FOR SOIL BASED BLOCKS USED GENERAL BUILDING CONSTRUCTION 1.1 This standard covers the requirements and test for soil based blocks for use in general building construction.
