APPLICATION OF STANDARD PENETRATION TEST TO THE FORMATION IDENTIFICATION OF SAND LIQUEFACTION IN THE YELLOW RIVER BASIN
Taking a vehicle depot of Jinan Urban Rail Transit Line 6 as an example,the standard penetration test was used to collect the number of hammer blows at the test points of the dynamic compaction and non dynamic compaction areas on the engineering site.Based on the calculation and discrimination method of sand liquefaction,the sand liquefaction situation in each area was compared and analyzed.The feasibility of using the standard pen-etration test as a discrimination method for the liquefaction phenomenon of sandy soil layers in the Yellow River Basin rail transit industry has been verified through engineering examples,in order to provide safety guarantees and reference basis for rail transit engineering construction.
