Abstract
A highway was constructed in Jiangxi Province, China, through a mountainous area. Some sections of the highway went through valleys where a soft clay layer 6–8·5 m deep was encountered. A new explosive method was developed and adopted for this project. The method uses the energy of the explosion to remove the soft clay and replace it with crushed stones. Explosive charges are placed in the soil to be improved according to a specific pattern. Crushed stones are piled up next to the area where the charges are installed. The explosion creates cavities in the soil and causes the pile of crushed stones to slide into the exploded area. The detail of the method and its application to the highway project are described. The effectiveness of the method is evaluated using borehole exploration, plate load tests and groundprobing radar tests.
期刊介绍:
The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
