摘要
天津市滨海地区的地下水含有较多的腐蚀性物质。作为基坑支护或复合地基的水泥土搅拌桩处于具有侵蚀性离子的环境中。利用试验模拟侵蚀性离子的存在,对不同离子浓度、不同水泥掺量的水泥土试件进行试验研究,结果表明其对水泥土强度有不同的影响。针对试验结果提出了技术建议。
There are many corrosive substances in the underground water ofTianjin Binhai area. The cement-soil piles, which act as foundation pit bracing or compound foundation, are surrounded by an environment of corrosive ions. Through erosion mechanism analysis and experiment simulation of existence of corrosive ions, experimental study is performed on cement-soil specimens with different ion concentrations and different cement mixing amounts. Results show that it has different effect on cement-soil strength. Technical recommendations are also given based on test results.
