DISCUSSION ON OVERBURDEN PRESSURE TO AND ANTI-COLLAPSING STRENGTH OF THE CASING PIPE
The overburden pressure and its side effect as wellas the pressure from clay swelling to the φ529 mm casing pipe in a bore hole are discussed in the paper. The calculating method of the anti-collapsing strength of large-size casing pipe is introduced. And one casing trouble in the field site was successfully solved by using the calculating methed.
