Construction of a new highway embankment on the soft clay soil treatment by stone columns in Malaysia

To continue of the second phase of the east coast expressway between kuantan and kula terengganu in malaysia system innovative solution are required. in this new phase there are embankment region has been subjected to extensive soft clay soil. these comprise typically of clayey silts of very high water content and undrained shear strengths in the range of 8 to 11 kpa to depths of up to 8m. to support an embankment height of up to 12 m,were filled and thereafter vibro replacement treatment was carried out to treat the very soft soil. extensive instrumentation using rod settlement gauges,inclinometers and piezometers were installed to monitor the performance of the vibro replacement treatment. this paper reports on aspects of design,installation and the measured results from the instrumentation scheme. © school of engineering,taylor's university.
