风化岩地区嵌岩短桩工作性状试验研究

依托青岛地区拆迁安置工程对桩端位于强风化岩上的人工挖孔灌注短桩进行研究,静载试验结果表明,岩基地区嵌岩短桩沉降量不大,具有较好的承载能力,并给出了此类地区人工挖孔桩最短桩长的建议值,研究结果有助于进一步了解风化岩地基嵌岩短桩的工作性状,具有一定的工程实践意义。

Research on working characteristics tests of rock-embedded short piles at decomposed rock areas

Based on the arrangement for the relocation households in Qingdao,the study researches the manual digging cast-in-place short piles whose pile ends locate at the strong decomposed rock,proves by the static experiments that the settlement of the embedded short piles at the rock foundation areas is small,so it has better loading capacity,and proves the suggested value for the shortest piles of the manual digging piles,and results of the research further explains the working performance of the embedded short piles at the decomposed rock,so it has certain engineering practice significance.
