Flat Dilatometer Tests in the Till Soils of Stabatiskes Site The biggest part of territory of Lithuania is covered of till. For the most detailed researches of soil there it is necessary to pick–up mostly modern and exact geotechnical research methods. The outside research methods are used to get the geotechnical characteristics. One of the most popular research methods in the world is dilatometer test. This one is not the most useful in Lithuania, so that was the reason and decision to analyze the usage of dilatometers test for till soils in Lithuania. The work object – till soils in the territory of Lithuania. Testing soils place – Ignalina nuclear power plant radioactive waste within the territory of Stabatiškės site. The aim of paper – the date processing of material index (ID), overconsolidation ratio (OCR) and dilatometer modulus (ED), reliability evaluations, the correlations with other test methods (CPT, DPSH). The work tasks are - • to check and introduce the method of dilatometer test (DMT); • to make an accountings of research data; • to identify the correlation relation in till soils in Lithuania between dilatometer test and cone penetration test; • to estimate the geotechnical characteristics then using correlation dependencies. After analyzing the operating principles and the usage opportunities of dilatometer test, counted clay soil geotechnical characteristics using MS Microsoft excel, dilatometers test was compared with cone penetration test, laboratories and also dynamic penetration test. The last one does not has any relation with dilatometer test, so the counting’s not given. The results shows, that DMT method can be fully used for soil tests in Lithuania’s territory to get geotechnical characteristics not only of till soils, but also of sand soils. |
