The paper is about the fact that the sandstones is narrow and small,with low continuity and scattered distribution and that there are plenty of muddy siltstones between sandstones in poky underwater distributary channel.

According to characteristic of softening of the strongly weathering muddy siltstone core,geological reasons resulted in the quality accident of pile foundation No.

Study on the weathering characteristics of Cretaceous argillaceous siltstone

Cretaceous argillaceous siltstone in Changsha district is a kind of soft rock with the features of weak diagenetic process,and it is suspcetible to weathering and can be easily disintegrated.

Therefore, on the base of the geological characteristics is that a great deal of argillaceous siltstone existing over the intermittent sand bodies.

The movement regulation of silty sediment close to Jintang Port area at each stage of sandretaining dike formation was emphatically inquired in the paper for seeking the reasonable layout of sandretaining dike.

Study on weathering characteristics of Cretaceous silty mudstone along the expressway from Changde to Jishou

In Changcha city silty mudstone, from which mainly occurred moderatly decomposed rock and slightly decomposed rock, is widespread during Cretaceous to Eogene system.
