Abstract:Research purposes:The pile—mesh compound structure is used for the deep soft soil subgrade of high—speed railway and its design is different from that for other engineering.There is no standard to follow in China currenfly.Although there are corresponding norlTIS in foreign countries,but their calculation results vary much,SO it is necessary to research and analyze their applicability.In this paper,by doing the tests,the pile—soil stress and the change law of pile—soil stress ratio with increase of the height of filling soil aye analyzed and the applicability of calculation method stipulated in foreign norms for pile—soil stress is verified with the test results.
Research conclusions: The test results show that pile—-soil stress ratio becomes large with increase of height of filling soil,the law of pile—soil stress obtained with the Germany norm is in line with the actual situation and the calculation results meet the requirement of computing accuracy,thus the Germany nolTn can be used for calculating the pile—soil stress.
