Similarity of shallow foundations according to ČSN 73 1001

pages 170 - +4p., full text

Now, that the translation into Czech and the National Annex of EC7-1 (EUROCODE 7 - Geotechnical design, Part 1: General rules) are carried out it seems convenient to make a broad comparative analysis of the EC7-1 and SN 73 1001 design procedures. The calculating procedure according to SN 73 1001 requires 8 inputs, the similar procedure according to EC7-1 requires 10 inputs. These numbers of inputs yield a huge number of combinations for a comparative analysis. The paper deals with a similarity solution of bearing capacity of shallow foundations according to SN 73 1001. The solution should form the base of the comparative analysis base for simpler numerical analysing. 1 Introduction The Czech standard SN 73 1001 “Subsoil under shallow foundations” is the oldest Czech LSD standard (1966). It was slightly amended several times but its original creators have done very good work. The standard is still of high professional level and is widely used by practicing professionals. Its long-term application of the standard has granted applying professionals much knowledge and certainty. The standard contains not only the requirements and instructions for the design of shallow foundations, but also a complete set of important and verified tables of soil classification and soil material parameters. Now, that the translation into Czech and the National Annex of EC7-1 (EUROCODE 7 - Geotechnical design, Part 1: General rules) are carried out it seems convenient to make a broad comparative analysis of the EC7-1 and SN 73 1001 design procedures. The calculating procedure according to SN 73 1001 requires 8 inputs, similar procedure according to EC7-1 requires 10 inputs. These numbers of inputs yield a huge number of combinations for a comparative analysis. Most of them are due to geotechnical material parameters (especially angle of soil resistance and cohesion) which can vary broadly and their influence at bearing capacity is strong. An easier approach to problem solution is provided by the theory of similarity. The paper deals with a similarity solution of bearing capacity of shallow foundations according to SN 73 1001. The solution should form the basis comparative analysis for simpler numerical analysing.
