Based on Tongluoshan and Mingyueshan tunnels��the authors study the shared ratio of pressure in secondary lining of highway tunnel�� Through the comparison by surrounding rock pressure measured values with calculated values of Pu's theory��Terzaghi theory and deep-buried surrounding rock pressure of highway tunnel design specification��the results show that calculated values of III-class����-class and V-class surrounding rock pressure are relatively in accordance with the practically measured values�� By analyzing the field measured data of the surrounding rock pressure��and contact pressure between primary support and secondary lining��it can be concluded that the shared ratios of pressure in secondary lining of III-class ( deep-buried) ����-class ( deep-buried) ��V-class ( deep-buried) and V-class surrounding rocks ( shallow-buried) are 29. 20%��35. 28%��41. 38% and 32. 17%�� respectively�� This research plays a theoretical role in guiding the design of highway tunnel��
