EVALUATION ON THE RESULTS OF MONITORING OF LONG-TERM SETTLEMENT OF THE EMBANKMENT FOR HIGHWAYS IN BANGKOK

In the suburbs of Bangkok, construction of new inter-city highways and widening of existing highways have been extensively carried out to relieve chronic traffic congestion. Since Central Thailand is mostly composed of soft soil, ground improvement and restriction of settlement have been a technically important issue for the construction of embankments for highways. The Japan-Thailand Joint Study Project on Soft Clay Foundation between the Department of Highways (DOH) and JICA, which started in January 1996, contributed to the transfer of technology to cope with soft soil (including methods for investigation, design, construction, quality control and numerical analysis) and studied ground improvement methods that suit the conditions in Thailand. Based on the results of the monitoring of long-term settlement, which was conducted on the embankments for highways already in operation, this report first describes the stabilization of the ground behind abutments, and the effects of and design for ground improvement, which are used for restricting settlement. In addition, at improved or widened sections on existing highways whose foundation ground was improved by the low-improvement-ratio deep mixing method, long-term monitoring of differential settlement between the centres of the soil-cement columns and soil between the columns was conducted, and the effects of this improvement method were also evaluated.
