Bearing capacity of Helical pile on peat soil can be obtained from cone penetration test (CPT).Bearing capacity based on CPT data is calculated by Bustamante & Gianeselli (LCPC) method,Schmertmann method, method Meyerhoff, Price & Wardle method, and Tumay & Fakhroo method. Meanwhile, there are two methods based on peat soil mechanisms to determine the bearing capacity of the helical pile such a…
