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.
