| Abstract | This study is conducted to develop the correlation of the soil parameters for the bored pile design through pile load test in Yangon. Bored piling has been extensively used for supporting new high - rise buildings in Yangon. Because of uncertainty in quality of building construction and foundations by various companies, the Myanmar Gove rnment had established the Committee for Quality Control of High - rise Building Projects (CQHP) to oversee the quality of building works including foundations. According to the regulations on pile foundation, static pile load tests shall be performed prior to construction for verification of pile design and performance. Additional pile load tests on working piles shall also be conducted as part of the quality control requirements. With these pile load test results and the soil boring data, the empirical correlation of the SPT N value and the skin friction is proposed for the bored piles in Yangon subsoils. The results showed well agreement with the results from other countries which have the similar soil properties. However, the relationship between SPT N value and the end bearing cannot be developed in this study as the end bearing was not fully mobilized. The alpha and beta values for the simplified static formula also back - calculated in this study. Due to the limitation of the data, the alpha value is back - calculated based on the relationship between SPT N value and skin friction. These values can be used in the static formula to determine the acceptable values of the ultimate loads. The strain - dependent secant modulus for interpretation of load from strain values also determined in this study from pile load test and the uniaxial compression test. The results from these two showed acceptable agreement. For the interpretation of the ultimate load from pile load test, Chin method, Mazurkiewicz method an d Fleming method is used in this study. Based on the results, Chin method has the good correlations with the ultimate pile capacity estimated from SPT N values and it gave the reasonable results than other two methods |
