Abstract

Experience gained during several decades shows that the loess soil in some cases undergoes structural collapse and subsidence due to inundation and that in some other cases the sensitivity of loess to the collapse is considerably less pronounced. In this paper the behaviour of three 12 story buildings A, B and C, of the same static system and the identical shapes have been analyzed. The measurement of settlements of building A over a period of 10 years indicate that the values were situated between the limits 9 cm to 13 cm, and that they are larger than the calculated values, but there was no damage reported in this case. However, the measured settlements of building B over the same period of time were considerably larger, reaching 46 to 51 cm, causing severe damages of the building. In order to find the explanation for such behaviour of loess subsoil, the additional field and laboratory testing of loess have been carried out. Some of the obtained results are presented in this paper.

Differential Settlement of Foundations on Loess

Chicago, Illinois

Experience gained during several decades shows that the loess soil in some cases undergoes structural collapse and subsidence due to inundation and that in some other cases the sensitivity of loess to the collapse is considerably less pronounced. In this paper the behaviour of three 12 story buildings A, B and C, of the same static system and the identical shapes have been analyzed. The measurement of settlements of building A over a period of 10 years indicate that the values were situated between the limits 9 cm to 13 cm, and that they are larger than the calculated values, but there was no damage reported in this case. However, the measured settlements of building B over the same period of time were considerably larger, reaching 46 to 51 cm, causing severe damages of the building. In order to find the explanation for such behaviour of loess subsoil, the additional field and laboratory testing of loess have been carried out. Some of the obtained results are presented in this paper.
