泥炭质土中腐殖酸对泥浆性能的影响

The Effect of Humic Acid in Peaty Soil on Mud Performance

针对在泥炭质土中,泥浆护壁灌注桩的泥浆配比问题进行研究。对泥炭质土中高有机质含量、高腐殖酸含量的特点进行处理。针对性选取椰壳活性炭、木质活性炭、氢氧化钠、腐殖酸钠等多种物质进行多组别泥浆性能测试试验。尝试降低泥炭质土中由于高腐殖酸的存在,对护壁泥浆产生的不利影响。通过大量试验对比及分析验证,筛选出氢氧化钾和氢氧化钠溶液对于泥炭质土介质中护壁泥浆性能的改善具有良好的效果。

This article focuses on the study of the slurry ratio of the mud-protected cast-in-place pile in peat soil. Treat the characteristics of high organic matter content and high humic acid content in peaty soil. Targeted selection of coconut shell activated carbon, wood activated carbon, sodium hydroxide, sodium humate and other substances for multi-group mud performance test experiments. Try to reduce the adverse effects of high humic acid in the peat soil on the wall protection mud. Through a large number of experimental comparisons and analysis verifications, it was screened out that potassium hydroxide and sodium hydroxide solutions have a good effect on the improvement of the performance of the wall protection mud in the peaty soil medium.
