provisions
Indoor test item of nature of geotechnique and test method should be as per provisions in this section， specific operation and test instrument be according with the provisions in current state standard, Standard for Soil Test Method (GB/T 50123) and state standard, Standard for Test Method of Engineering Rock Mass ( GB/T 50266 ), Parameters in valuation of geotechnical Engineering may consistent results of in-situ test or result of prototype observation re-analysis comparing provisions that be modified.
Test items and test methods should be in accordance with project request and determined by character of rock and soil properties. It should concern about rock and soil stress field in-situ and stress history, new stress field and new boundary conditions caused by project activities, when it is necessary, make test conditions approach reality as far as possible; should pay attention to rock and soil heterogeneity, non-isotropy and non-continuity. And pay attention to the rock mass and soil mass in engineering behaviour different from rock and soil samples.
Special test method statement be composed for special test items..
Megascopic method and brief describing be made for rock and soil significant behaviour before making test specimens
