Risk Example of Passive Pressure according to Procedures of EC 7-1 and ČSN 73 0037
Koudelka, Petr
The paper targets a problem of theoretical base of the Annex C of EC 7-1 a ČSN 73 0037 comparing instruction calculation results to results of a physical experiment E5/0,2, i.e. pressure at rest and passive pressure of ideally non-cohesive sand.
Process of lateral passive pressure acting in a sandy mass
Koudelka, Petr
The paper presents the results of physical experiment both with the passive pressure and the pressure at rest of the ideally non-cohesive sand on a retaining wall rotated about the top. The results are analysed and compared according to relevant requirements and recommendations of the final draft of EC 7-1(2004) and ČSN 73 0037. A preparation state of a next repeated physical experiment with passive pressure and pressure at rest to prove the results is mentioned.
Design Analysis According to EUROCODE 7-1 - Pile Foundations
Koudelka, Petr
The Paper shows briefly the history and development of the Ultimate Limit State Design of bored piles. Attention focuses on a comparative analysis of the tabular design values and the results of numerical analysis and their suitability for the Czech National Annex of EC7-1. The analysis results are compared with tabular design values of the relevant Czech standard.
Dissaccordance of EC7-1 and CSN 73 0037 to Knowledges aboutEarth Pressure
Koudelka, Petr
The paper shows objections against the contemporary conventional theory of earth pressure and standards and designs a non-conventional conception of the lateral pressure on the advanced comprehensive non-linear dependence based. The conception takes into account the singularity of pressure at rest and the shear strength decrease after the peak value.
