工程场地及其附近的土或水(地表水或地下水)对建筑材料的腐蚀性强弱的判别结果,影响到工程设计对水泥类型的选用,基础类型的选择以及采取必要的防腐措施等方面,最终直接影响到工程总造价,因此工程勘察阶段应对场地及其附近的土或水进行详细的分析和评价.为了定量分析地基土内Mg2+、SO42-、Cl-质量比随深度的变化规律,以麻黄山乡后洼村境内唐庄110 k V变电站工程场地为例,取勘探点一定深度内土样进行测定,并采用粒子群优化算法对试验成果作以解析,从而对该地区的Mg2+、SO42-、Cl-质量比随深度的变化规律提供参考.结果表明,Mg2+、SO42-、Cl-质量比随深度呈线性减小.
Construction site and its vicinity of soil or water (surface water or groundwater) to determine the corrosiveness of the construction materials, affecting the engineering design of the type of cement selection, the choice of basic types and the necessary anti-corrosion measures taken, etc., So the total cost of the project will be directly affected, so the soil and water near the site and its vicinity should be analyzed and evaluated in detail in order to quantitatively analyze the variation law of the mass ratio of Mg2 +, SO42- and Cl- in the subsoil with depth, Taking the site of Houzhuang 110 kv transformer substation in Houwa village of Mahuangshan Township as an example, the soil samples within a certain depth of the exploration site were measured, and the particle swarm optimization algorithm was used to analyze the test results, so that the Mg2 +, SO42 - and Cl -, the results show that the mass ratio of Mg2 +, SO42- and Cl- decreases linearly with depth.
