Abstract: Argillaceous siltstone is a kind of soft rock, which is widespread during Cretaceous to Eogene in China. The potential bearing capacity of this rock is relatively larger. But the bearing capacity evaluated with current Code is quite different to that obtained on site test. The correlation between pressuremeter test (PMT) and uniaxial compressive test on sedimentary rock are studied; and the correlation equations are established for characteristic parameters of PMT and compressive strength. The result of analysis shows that PMT is rather effective for determining the bearing capacity of this kind of soft rocks and is deserved to be applied to practical problems such as those on soft rocks.

Key words: argillaceous siltstone, uniaxial compressive test, PMT, loading test, characteristic value of bearing capacity
