修正快压法是复合地基载荷试验的新方法。该方法的试验要点是:每级荷载均要求加压1h,并测读其相应的沉降量;当加压至设计荷载时,尚应压至规范规定的相对稳定标准;以后各级荷载仍加压1h,直至破坏或规范规定的卸荷标准。论文详细分析了该方法的理论依据,并与常规慢压法载荷试验进行了对比,分析了工程应用的效果。分析结果表明,修正快压法应用于复合地基载荷试验不但可以提高工效而且偏于安全,值得工程中推广应用。
Correction of fast-pressure method is a new method of composite foundation load test. The test points of the method are as follows: the load of each level requires 1 h of pressurization and the corresponding settlement is measured; when it is pressurized to the designed load, it should be pressed to the relatively stable standard prescribed by the code; Pressure 1h, until the destruction or standard unloading standards. The paper analyzes the theoretical basis of the method in detail and compares with the conventional slow-pressure load test, and analyzes the effect of engineering application. The analysis results show that the modified quick-pressure method applied to the composite foundation load test can not only improve the work efficiency but also bias the safety, which is worth popularizing and applying in the project.
