What is High Strain Dynamic Load Testing?
At present, there are five methods for pile foundation testing. High-strain dynamic load testing is the only testing method that can test both bearing capacity and pile integrity. In Southeast Asia, high strain dynamic load test has become one of the main methods of pile foundation testing.
China's Guangdong region is located on the coast, with a wide distribution of soft soil areas, a large construction scale, and a large amount of piles. High strain testing has been widely used for many years.
High strain foundation testing technology is used all over the world. The technology of high-strain dynamic load testing has developed rapidly. At present, the hammer weight of Guangdong's high-strain testing has reached 60 tons.
High strain testing is more economical than static load testing, the number of sampling tests is higher than static load testing, and the testing cost is much lower than static load testing. In recent years, high-strain testing technology has developed rapidly, the accuracy of test and judgment is rising, and the scope of application is becoming wider and wider. High strain testing has been recognized by relevant government departments and all aspects of society.
Therefore, high strain is a more scientific and better method. For the pile type that conforms to the high-strain testing technology, high-strain is used as the pile bearing capacity testing, instead of the static load test locally. From the advanced nature of the method, the overall control of the project quality, and the saving of social resources, it is very worthy of promotion.
What should the dynamic load testing agency do?
As an engineering construction testing institution, the first is the integrity of the practitioners and engineers. The second is service awareness. Testing institutions are all defined as high-tech modern service industries. The third is the improvement of testing ability. The testing institutions have gradually realized enterpriseization and marketization.
