| Popis: | 95 The in-situ stress measurements can be obtained by using the Hydraulic Tests on Preexisting Fractures (HTPF) method. The HF method is tailored for problems that the fracture plane has to be perpendicular to the ground surface. The problem with inclined fractures is still applicable for the HTPF method. Knowing the stress distribution using the above method is quite helpful for the selection of engineering programming and construction method and to effectively capture the site safety and its structural stability when under construction. All the analytical data of in-situ stress measurements used in this research were obtained from the tests conducted in France using hydraulic tests. The HTPF method was employed for the stress analysis of the data. The analysis result from this research was compared with the original one as shown in the published papers in order to validate the development of the computer code HTPF2007 in this research. In addition, the liability of the in-situ test data was further examined by substituting the calculated results and partial test data and thereby hopefully gave the possible criterion for the selection of the test data. |
