| Abstract: | The sedimentary environment of the bedrock foundation area is complex,so we should choose suitable drilling technology and equipment,analyze the abnormal phenomena in drilling,and divide reasonably the residual soil and weathered layer;check the site record and compare them with the core samples to ensure accurate layering and naming;pay attention to the application of heavy dynamic penetration test;estimate reasonabily the bearing capacity of the weathered layer and determine the pile foundation design parameters and choose the appropriate estimate calculation method for the bearing capacity of rock-socketed bored piles. |

| Keywords: | residual soil weathered layer heavy dynamic penetration bearing capacity of foundation rock-socketed bored pile bearing capacity of single pile |
