ACCESS ROAD IN THE EXTREME CONDITION BASED ON THE GEOTECHNICAL AND STRUCTURAL PERSPECTIVES (CASE STUDY IN GUNUNGPATI DISTRICT, SEMARANG-CENTRAL JAVA)

The Access is the backbone of zona development. Road infrastructure has an important part of the activities pattern in the urban or sub urban area. Gunungpati district is the one of conservation zone in Semarang, central java which has extreme geographical performance. Some problems are unstable slope, risk of soilcreep, poor drainage system, even system structure expensively matter in the settlement area. In the future the South Ring Road will be built across the Gunungpati district it mean that problems must be solved comprehensively. Some previews study about Gunungpati and simulation with some approach like isoprice map, trajectory of public transport, soil properties analysis with geotechnical modelling and structural model are briefly describe the threatment efforts of the extreme condition. The result of the study are the alternatives to treat the condition of transportation system, geotechnical phenomenon and safety of structural system for settlement area
