As large scale civil engineering constructions go on pushed by economic de-velopment, problems are emerging with regard to resource utilization and environmental preservation due to construction materials. In this circumstance, PET bottle as construction materials will make environment-friendly approach to more efficient recycling of resources. In this study, to utilize PET bottle as substitute by EPS, uniaxial test was performed on PET bottle, and compressive strengths were respectively compared and analyzed depending on whether dry ice is added or not. As a result, it was proposed that it can be applied to the field as substitute by EPS.

The safety rate according to the location change of the trench crossing the soft ground counterweight fill can be interpreted. Here, the recording safety rate in which the soft ground depth will become intense the height of the dam body will be enhanced reduces. And the circular slip boundary line of the dam body is formed in the location which the safety rate reduces drastically and the common-point has to avoid the establishment of the transverse direction trench in the circular slip boundary line location.
