Method for determining lime mixing amount ratio in expansive soil
The invention discloses a method for determining a lime mixing amount ratio in expansive soil, relates to the technical field of civil engineering, and aims at solving the problems that in the relatedart, the expansive soil is improved through the lime, and after lime metering exceeds a certain value, the mechanical index and the water stability of the lime stabilized soil are reduced, and the method comprises the following steps that S1, taking the expansive soil and the lime; S2, preparing an EDTA standard titer line according to the water content controlled by construction; S3, taking 3-6%of lime, and uniformly mixing with the lime to obtain a mixed soil sample; S4, culturing bacillus megaterium liquid and preparing cementing liquid; S5, adding diluted 60-80% bacillus megaterium liquid into the mixed soil sample, uniformly stirring, and standing for 2 hours; S6, after 2 hours, sucking out the bacillus megatherium liquid, adding 60-80% of cementing liquid, continuing to solidify, uniformly stirring, and standing for 22 hours; and S7, sucking out the bacillus megaterium liquid and the cementing liquid, and repeating the steps S4 and S5 seven times.
本申请公开了一种膨胀土中石灰掺量比的确定方法，涉及土木工程技术领域，旨在解决相关技术中通过石灰改良膨胀土，当石灰计量超过某一值后，石灰稳定土的力学指标和水稳定性下降的问题，包括以下步骤S1、取膨胀土和石灰；S2、根据施工控制的含水量，制备EDTA标准滴定时程线；S3、取3‑6％石灰与之进行混合匀匀，得到混合土样；S4、培养巨大芽孢杆菌菌液并配置胶结液；S5、在混合土样中加入经稀释的60‑80％巨大芽孢杆菌菌液，搅拌均匀后，静置2小时；S6、2小时后，吸出巨大芽孢杆菌菌液，再加入60‑80％胶结液继续固化，搅拌均匀后，静置22小时；S7、吸出巨大芽孢杆菌菌液和胶结液，同时重复步骤S4、S5七次。
