A Bearing Capacity of Bamboo Cluster Pile on Saturated Soft Soil Based on the Direct load Test and CPT’S Data

One of the constructions that can be used to overcome problem soft soil is through pile mattress bamboo construction. This construction consists arranged as mattresses and cluster piles. The several culms tied together (cluster pile). Cluster capabilities are not analysedfor strength result in wastage or failure. Hence, this study was intended analysethe ability clusters recorded direct observation compare them based on sonder (CPT) data. method carried out by model at research site. observed with a length 8 m, inserted into then vertical loading until supports it collapses. There 3 types pile, namely piles C3, C4, C7. results showed ultimate bearing capacity load test relatively same calculated Thus, established (Pult) which determined using equation, Pult= 7.4056Ac, where Pultin (kg), Ac area (cm2).
