| Abstract: | The overburden pressure and its side effect as wellas the pressure from clay swelling to the 529 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. |
