Abstract:This paper analyzes the deformation mechanism of CFG pile composite ground under road embankment. Based on the assumed settlement model and the distribution of friction of pile, a method for settlement calculation of the interaction of pile-soil-cushion is deduced. A trial case shows that the predictions given by the derived formulas agree well with field measurements.

Abstract:In this paper, the application of compaction grouting in Anqing power plant, which is aiming at eliminating the liquefaction probability of ground and increasing the ground capacity, is introduced. From the analysis of the experiment data, compaction grouting can meet with the requirements of the design. It is proved that compaction grouting is a useful method to treat liquefiable ground, which is especially true when the ground is narrow.

Abstract:The paper introduces Hua'nan Highway engineering in Guangzhou city. The project includes several bridges, in which totally 112 pieces drill (wash) bored piles, with 1.0 m, 1.5 m and 1.8 m in diameter, 44 ~ 51 m in length, were adopted as the foundations. Because geological conditions varies largely, some strata contain mud layer and Karst cave etc. and what’s more, main bridge locating in water at the depth of 8 m, some difficulties were dealt with.

Abstract:Main reason of uneven abrasion on the work layer of impregnated diamond bit is proved through theoretical analysis and application test. Adopting rectangle water mouth makes diamond cutting burden heavier along radius line from outside to inside and causes the rapid abrasion to works layer when diamonds in bit are distributed evenly and in the same quality.
