摘要	Taking the cast-in-place pile construction project in the new campus of a University that locates in an area with silt-rock fill soil as an example, 15 cast-in-place piles were constructed using five drilling schemes and tested using full-scale tests. Data were recorded in the process of the test. The results were detected using acoustic transmission method and vertical compression static load test. Taking engineering experience into account, percussion drill method was considered as the most suitable for the construction of cast-in-place piles in areas with silt-rock fill soil. Then in-situ full-scale test of burial depth of steel casing were carried out on 21 piles which were constructed using percussion drill method and divided into 3 groups. The optimal burial depth of steel casing and the limitations of mud protection wall in rock-fill and silt soil were obtained according to the construct cost of one pile, construction period and filling coefficient. Based on the above achievements, a set of effective, high-efficient, reliable, economic and environmental-friendly construction technique was proposed and applied in the construction of 3867 cast-in-place piles in the campus. The construction indicators and actual result were satisfactory. The results can offer a reference for the construction of cast-in-place piles in areas with silt-rock fill soil. © 2019, Cefin Publishing House. All rights reserved.
