Abstract

Understanding the thermo-mechanical behavior of saturated fine grained soils has become a very important topic whenever the geotechnical problems involve thermal effects. Previous research works in literature show that by subjecting the saturated fine-grained soils to temperature less than water boiling point volumetric and shear strength changes are induced. The thermally induced changes have been attributed to the physico-chemical change at the microscopic level. The aim of this research is to study the thermo-mechanical behavior of natural soft Bangkok clay, with temperature up to 90OC. Intensive laboratory tests using modified oedometer apparatus were conducted to investigate this behavior. The testing program was directed to study the effect of heat on the thermally induced volume change at different temperature and stress conditions, the thermal evolution of the preconsolidation pressure, the induced overconsolidation behavior after heating/cooling cycle, and the effect of temperature on the hydraulic conductivity. The experiments carried out on soft Bangkok clay provided some additional useful data on the thermo-mechanical behavior of the soft deposits. The results of this research work have been compared with those in literature with different clay types to generalize the thermo-mechanical behavior of the saturated clays.

Abstract

The strong earthquake on April 25, 2015 (7.8 Mw) and the aftershock on May 12, 2015 (7.3 Mw) claimed the lives of 8,659 people, plus 21,150 people injured and huge economic loss together with serious damages on eight World Heritage sites. Our two field surveys in the month of from May 9-21, 2015 and 19-23 July, 2015 revealed understanding of damages to traditional towns, historical monuments, and modern buildings. Regionally, damages on buildings are confined to the traditional houses which are remnants of or renovated after the 8.1 magnitude 1934 AD earthquake. Widespread cases of inadequate engineering and construction practices for RCC (Reinforced Cement Concrete) buildings and renovated old buildings have been severely affected. The affected region includes the main shock along the 150 km long rupture zone towards east. The aftershock reached farther south at a shallower depth towards the end of the eastern rupture zone. As a result damages inflicted in the structures from both quakes revealed different shaking directions. The April 25 main shock caused eastward leaning structures while May 12 aftershock caused southward leaning and/collapsed structures. It is important to identify whether the direction is due to aftershock at the end of initial rupture zone or if it represents a newly exposed fault.
