| description | A tectonic earthquake with the magnitude of 6.3 Mw shook Yogyakarta area on May 27, 2006. Seismic response of soil layers that caused by earthquake is an earthquake ground motion parameters. Soil has a very important role as conductor of vibrations from the epicenter to the soil surface. Response of soil that has a smaller stiffness will be different with soil that has a greater stiffness. Parameters on soil types which include the state of local geology and soil conditions also resulted differences in response of buildings caused by the earthquake in some places.
A study was conducted to determine the dynamic respons of soil layers in some areas using the geotechnical data and analysis respons of subsoil using dynamics analysis method with spectrum variety structure of Multi Degree of Freedom (MDOF) by modeling the soil layer as Shear Building. The data used was the Standard Penetration Test data and laboratory tests that form soil properties data on the 4 point reviews that spread in Bantul region where occurs lateral spreading and sand boils in that area. At particular depth of soil layer, soil properties value was determined by using the correlation of SPT data at the point of reviews. Analysis of the dynamic behavior of the soil was done by determine the amount of bedrock acceleration based on earthquake map SNI 1726-2012. At the stage of dynamic behavior of soil analysis was also used MATLAB software as a tool in the calculation.
The results shows that the stiffness of soil tends to become smaller near surface so that resulted small angular frequency (�) and great period of vibration (T) in the topsoil so caused the acceleration of each soil layer on topsoil at analysis location get smaller than the acceleration of the basic boundary analysis. Besides, soil data on the 4 point reviews mojority is sandy soil where the value of plasticity index (PI) is very small or even close to zero and sand soil has great damping ratio so the acceleration of each soil layer at analysis location near to the surface get smaller than the acceleration of the basic boundary analysis. Dynamic property of soil that form shear modulus (G) and damping ratio (D) resulted soil respons that cause by earthquake declined becase there are reduction on earthquake wave. In this analysis was also summarized the results of liquefaction potensial test with shaking table where sand sampling locations at Kali Opak Imogiri was not far from one of soil dynamic behavior analysis location in Tempuran, so the test results of liquefaction with shaking table can be stated that in Tempuran area occur liquefaction. |
