Progressive Lifting of Shallow Sewers Due to Frost Heave Actions: Investigation of a Lumped Parameter Frost Heave Model

摘要: The objective of this report is to complete work undertaken at the University Minnesota in mid 1990's. This was directed developing an understanding frost heaves relationship lifting buried objects such as shallow sewers. critical findings field investigation were detailed a 1995 final by Ray Sterling, "Progressive Lifting Shallow Sewers: Field Investigation." Preliminary details modeling provided interim project and MS thesis Lingjun Hou, "An Investigation Lumped Parameter Frost Heave Model," published January 1994. current outline previous Hou's thesis. document should be seen complement original submitted Sterling 1995. central study lumped parameter heave model developed Blanchard Fremond. shows that porosity can generate accurate comparison with experiments feasible tool for effect freeze thaw on infrastructure.
