- Abstract:
- With the rapid advancement of the “One Belt,One Road” strategy,more and more Chinese companies went out to participate in the construction of foreign infrastructure projects.At present,the biggest engineering problem encountered by Chinese companies in the construction of foreign infrastructures is that the technical standards used in China and over the world are not consistent.This paper took the standard penetration test as the research object,and synthesized the existing research results,then analyzed and compared the applicable scope,correction method,test equipment,and the correlation of the standard penetration test of the domestic and international standard penetration test.The results show that domestic and international standard test is widely used,can be used to estimate soil related parameters and evaluate sand liquefaction,however the empirical relationship between soil parameters is different in China and over the world.The correction of the standard number of hits has a water table correction,rod length correction,overburden pressure correction,energy correction,different national standard penetration number correction methods.When the standard number of strokes is small,the difference between the number of standard strokes in each country is small.In actual engineering,the differences between them can be ignored.
