THE DISCUSSION OF EVALUATION ON COLLAPSIBILITY OF LOESS IN GUANZHONG AREA ON THE DIVERSION PIPELINE

Combine with the analysis on collapsibility of loess in different geomorphic unit and the discussion on the current specification we fount out that: Due to the lightening of the diversion pipeline, the value collapse settlement was little than which calculated with the laboratory test data; the incidence of groundwater variation on the collapsibility evaluation of different geomorphic unit was variant; we suggest that the foundation treatment methods of the buried set outdoor pool could be referenced on the buried pipe and box culvert, the difference of the correction factor in different geomorphic unit should be taken into account, and should review the value of the collapsibility in those project which load would be decreases.
