STUDY OF DIFFERENT APPLICATION EFFICIENCIES AND SIMULATION MODELS FOR MICROPILES ON SLOPES
Ching-Jiang Jeng, Chih-Chang Lin
This paper discusses the application of micropiles on slopes along constructions and castle walls in historical site maintenance. Using the PLAXIS finite element method to perform simulations. The attainable results include that underpinning and strengthening with inverted L-shaped micropiles in coordination with low-pressure grouting reinforcement can increase the safety factor of slopes along the castle wall of historical sites, improve the foundations of the castle walls to substantially reduce the total amount of displacement, significantly inhibit the settlement, and alleviate the subsidence trend of the foundation structure of castle walls. Likewise, gantry-style micropile reinforcement methods can enhance the safety factor, reduce the total amount of displacement, as well as inhibit and alleviate the soil settlement. In summary, micropiles can indeed be used to provide useful stability to the foundation and inhibit the displacement in order to strengthen the slope state along the castle walls of historical sites, where the working space is relatively narrow. It is anticipated that the analytical results of this paper can be used as a reference for similar projects.
