摘要：

To provide a reference for the design of pile foundations of bridges on the Xichang-Panzhihua expressway being constructed, the static loading tests and researches on the axial bearing capacity of 13 cast-in-situ piles set in Xigeda-rock were carried out at Xinjiu in Panzhihua and at Puba in Dechang. Xigeda-rock is an extremely soft rock with the special behaviors of softening, mashing and collapsing due to water, and this kind of rock abounds in a region as long as 90 km along this expressway. The experimental and research results show that Xigeda-rock can be used as the ground of pile foundations, and the construction quality is extremely important to their bearing capacity.
