用振冲法加固松软地基后,要进行加固效果的检测,现场静力荷载试验是检测加固效果的基本手段。大型载荷试验比较复杂,特别笨重,不经济,实施起来相当困难,因而未能推广。故作者致力于寻找载荷压板面积为0.25㎡与0.5㎡的小型载荷试验(以下简称小型载荷试验)与大型载荷试验两者的关系,试图用小型载荷试验取代大型载荷试验。
After the soft foundation is reinforced by vibroflotation method, the reinforcement effect should be tested. The static load test on site is the basic method to check the reinforcement effect. Large-scale load tests are more complex, particularly cumbersome, uneconomical, and very difficult to implement, so they have not been popularized. Therefore, the author devoted himself to finding the relationship between small load test (hereinafter referred to as small load test) and large load test where the load plate area is 0.25m2 and 0.5m2, trying to replace the large load test with a small load test.
