Description
Summary:The quality of cement mixing piles is closely related to the efficiency of soft soil reinforcement. The core sampling is the main method but not perfect on the origin identification of defect cement mixing piles. Combined with practical project, a assisting evaluation standard is set up through the test of standard piles that is used as a standard for the evaluation of defect piles. The results show that the quality of pile draft as well as the anthropic construction defects like the decrease of cement and mixing can be identified through the evaluation standard under complex soil situation.
