Guide to rock and soil descriptions / Руководство по описанию горных пород и почв

The purpose of this Geoguide is to present a recommended standard of good practice for the description of Hong Kong rocks and soils for engineering purposes. It is a companion document to Geoguide 2 : Guide to Site Investigation (GCO, 1987a). This Geoguide is aimed primarily at the practising civil or geotechnical engineer, but is also intended for use by geologists, engineering geologists and other professionals working inthe earth sciences. It has been prepared on the assumption that the user may not have any specialist knowledge of descriptive systems or methods.The overall structure and many individual text sections of this Geoguide are based on Section 8 of BS 5930 : 1981, Code of Practice for Site Investigations (BSI, 1981). This British Standard (BS) has been selected as the basic reference document for both this Geoguide and Geoguide 2, in the belief that many of its sections are applicable to Hong Kong conditions without the need for major modification. However, the layout of this document differs considerably from that of Section 8 of the BS, and a number of new text sections have been added, together with many more tables, figures and plates. These changes reflect not only differences of emphasis with regard to local geological conditions, but also the need for more illustration and explanation of geological terms for the non-specialist user. <...>
