摘要
针对地下水对混凝土分解性侵蚀指标pHs现行评价方法中存在水样间pHs横向没有可对比性和难以定量绘制pHs分解性侵蚀分区图等两大缺陷,推出了一个新的pHs分解性侵蚀判别式sk1,用编制的"地下水对混凝土分解性侵蚀判别式计算程序",完成了新定义的判别式sk1的计算,计算结果不但具备了水样间的每种分解性侵蚀横向对比的功能,而且还具备了定量绘制每种分解性侵蚀分区图和定量绘制3种分解性侵蚀综合评价迭加图的功能。通过实例应用,形象地印证了现行评价方法存在的缺陷及现推出的判别式、定量编绘侵蚀分区图的可行性。
There are two main limitations in current evaluation method of decomposable corrosion pHs for groundwater acting on concrete, one is the decomposable corrosion pHs of different water samples without lateral comparability, and the other is that it can not be quantificationally drawn in the division map of decomposable corrosion pHs. A new discriminant sk1 of decomposable corrosion pHs is deduced with the calculation process, which can well solve the calculation task of decomposable corrosion pHs for groundwater acting on concrete. The calculation result not only has lateral comparability, but also has the ability of drawing the superposition map of synthetical evaluation of three decomposable corrosion pHs quantificationally, An example shows the shortage of current evaluation method, the discriminant and its feasibility of drawing the division map of decomposable corrosion quantificationally.
