| Abstract | This study improves the soil stability of wastewater treatment ponds of Khon Buri Sugar Mills, located at Amphoe Khon Buri, Nakhon Ratchasima Province, Thailand. The wastewater treatment system consists of two areas. The first area contains 15 wastewater treatment ponds with a total area of 212 rai (83.8 acres). The second area has three wastewater treatment ponds with a total area of 103 rai (40.7 acres). The characteristic of local soil is dispersive soil with the degree of dispersive about 50.50 by double hydrometer test. The slope stabilization of ponds calculated using KUslope? program found that 11 ponds have the safety factor is less than 1.5. There are three methods that suitable for stabilization with surface protection including Buttress by Counter Berm, Sheet pile wall, and Cement Column. Using the hierarchy method, the study finds that the best suitable method of slope stabilization is Buttress by Counter Berm with surface protection. The weight of Counter Berm is to use soil-cement with a ratio of soil and cement is 7:1 by weight. The density of soil-cement is 1.95 g/cm3. After the improvement of slope stability, the safety factors of all slopes are more than 1.5. |
