Our population distributed unevenly between cities and rural areas. Urban constructions were developed to reach the sky, buildings are built higher and higher, and foundations are dig down deeper and deeper. There are not enough spaces between buildings in Taipei city with high residential density. As course and effect, buildings might be damaged and sloped when surroundings dig open foundations easily. There are different righting methods can be used, each has its pros and cons. How to select an appropriate righting method in different environmental factors, in order to gain cost-effective and reduce second damage happened on buildings. By using AHP(Analytic Hierarchy Process) to evaluate the engineering method of grout righting, and analyze its target value of the depth of ground improvement and the righting movement, in order to apply research result into engineering design projects. As the result from AHP evaluation, this research used DRJ(Double Packer Strainer、Rod method of Jacking) righting method in soft soil layers, In contrast to other two methods, DRJ would be more appropriated. Additionally, the target value of the depth of ground improvement and the righting movement could be applied on engineering righting projects’ calculation after analyzing through the research.
