Nondestructive test field survey for assessing the extent of ettringite-related damage in concrete bridges

By means of field sampling , laboratory test , field survey and data collection methods. The characteristics of expansive soil were studied. After analyzing the reasons for deformation and failure of expansive soil to buildings, effective treatment methods were put forward. Under the extreme drought climate condition, the buried depth of the foundation should be appropriately increased.

Component analysis, mechanical property test, field survey and finite element mechanical calculation were used to analyse and evaluate the deformation failure of the Guyed-V Tower link plate of a 500 kV transmission line. The results show that the main cause of the failure is the relaxation of the guy after right front guy or wire is subjected to a large impact towards the large side. The weak design of the link plate structure and the misfitting of angle steel are the indirect causes of the failure. The construction angle of anchor cable is larger than the design value, and the tension of anchor cable is low, which has a certain impact.
