Slope Stability Analysis and Protection of Mae Puem Riverbank

Abstract

Developing and improving the landscape of the Mae Puem River in Phayao Province. It is a development to use the natural resources of the river for maximum benefit for consumption. Occupation in the agricultural sector including houses The number of buildings along the banks of the Mae Puem River is increasing with the goal of economic development and restoring and balancing the ecosystem in the river. In the past until the present, the problems encountered in the Mae Pue River were the collapse of the river bank that lacked the stability of the soil slopes and it was also found that there were cracks ready to cause continuous collapse of the river bank.   However, in the study area there has not yet been a guideline for strengthening structures to protect river banks that have failed and lack the stability of the soil slopes appropriately according to engineering principles. Therefore, in this research, we focus on collecting data to analyze and find ways to protect riverbanks in an engineering style that is stable, strong and cost-effective in construction. Therefore, a survey was conducted to collect data on the nature of the disaster in the study area. Results of the preliminary survey. Most of the failures occurred in the form of sliding failure. The soil slope moved along the plane of the river bank. Collect soil data from drilling surveys. together with physical factors water flow rate Sudden reduction of water level at various levels To analyze the safety ratio of soil slope stability by using 2 computer programs. In the past until now, the programs that are widely used in soil slope stability analysis are Geoslope 2012 slope/w by Limit equilibrium method and Plaxis 2D by Finite element method. Both programs are software that can analyze the safety ratio of soil slope stability. Although there are different methods for analyzing data, Before the results are used for analysis in designing a structure to protect the Mae Pue River bank. For use to benefit in the construction of stable, permanent riverbank protection and as a guideline for relevant agencies in the future.
