While keeping an eye on geotechnical industry-related testing technologies and standards, it's inevitable that when using geophysical and pile static load test equipment, some frequently mentioned issues by colleagues or clients may arise. In this article, the GeoUnion editor compiles 3 common questions, with more to follow for your reference.
What is the pile foundation static load test equipment and pile foundation static load test?
The answer is: Static Load Test: A testing method for determining the vertical compressive, vertical tensile, or horizontal bearing capacity of a pile by applying axial compressive force, upward pull force, or horizontal force at different levels on the pile cap, respectively, and observing the settlement, upward displacement, or horizontal displacement of the pile's corresponding test points over time. The determination is based on the relationship between the load and displacement (i.e., the Q~S curve).
It is one of the most widely used methods for testing the bearing capacity of pile foundations (including composite foundations and natural foundations), and is generally recognized for its accuracy and reliability in test results. It has been included in the engineering specifications or regulations of pile foundation projects in various countries.
The桩基静载实验设备 employs various methods of artificial loading to simulate the actual working conditions of the foundation or substructure, testing its load-bearing performance and deformation characteristics after loading. Its significant advantage lies in the relatively close approximation to real-world loading conditions, its simplicity and ease of use, and the intuitiveness of the test results, which are easily understood and accepted by people. However, the scale and cost of the tests are relatively high.
Question 2: What types of tests are conducted on the pile foundation static load testing equipment?
Answer: Pier foundation static load test equipment test types: Divided by test object, it includes shallow soil surface plate load test, deep surface plate load test, composite soil foundation load test, rock foundation load test, pier (abutment) foundation load test, anchor (pile) test; Divided by loading method, it includes vertical compression test, vertical pull-out test, and horizontal load test.
Q3: What are the types of pile foundation static load test equipment?
Answer: Test Equipment Used: Jacks, load cells, displacement sensors, a percentage gauge, and of course, the static load tester.
