摘要
通过大孔径钢波纹管涵洞在东北季冻区的应用,解决了季冻区混凝土涵洞的冻融开裂及不均匀沉降问题。对大孔径钢波纹管涵洞管周土体温度进行测试,得出钢波纹管涵洞管周土体温度场变化规律。
Through the application of large - diameter steel corrugated pipe culverts in the northeastern seasonal frozen areas, the problems of freezing, thawing, cracking and uneven settlement of concrete culverts in seasonal frozen areas are solved. The variation pattern of temperature field of the soil around large - diameter steel corrugated pipe culvert tube is obtained by field tests.
