The static load test method of the pile foundation refers to the application of a load on the top of the pile to understand the interaction between the pile and the soil during the load application, and finally to determine the construction quality of the pile and determine the pile's construction quality by measuring the characteristics of the Q ~ S curve (ie settlement curve) Carrying capacity.
The static load test method is suitable for detecting the vertical compressive bearing capacity of a single pile.
Advantages and Disadvantages
1. The static load test method can be used to load the pile to failure, providing single pile bearing capacity data for design, as a design basis.
2. The static load test method of pile foundation is mainly to maintain the load method at a slow speed, the technology is simple, and the results are clear.
The detection time is long and the detection cost is high, and the matching work is troublesome, so this method is rarely used.
