摘要

In the paper, a study is conducted to pile foundation post-grouting and static load test, in which the tested value is used to compare with the standard of China, America and Europe. Taking Li-yuTuo bridge as study object, the trial piles - 3c2 and 3c4 with length of 33 meters and diameter of 1.2 meter are selected. The vertical bearing capacity of single pile is designed as 33000 kN which thereafter is enhanced using post-grouting. The on-site static load test is employed to evaluate the bearing capacity of pile foundation that is obtained being 39220 kN through self-balanced test. It is indicated through standard comparison that the bearing capacity calculated by China and America standard is akin to each other, turning to be excessively conservative and much less than the theoretical value of Europe. The Chinese standard shows bearing capacity after grouting is increased by 78.8 percent compared with pile foundation being not grouted. The post-grouting trial value is increased by 18.8 percent more than design value, 81.4 percent than theoretical value of general pile and 1.44 percent than theoretical value of post-grouting.
