塑性混凝土防渗墙由于其弹性模量较低，能适应砂卵石地基的变形，有较好的抗裂性和抗渗性，因此作为一种新型的防渗墙结构已在工程中得到了初步的推广应用．但是对于塑性混凝土这种新型墙体材料的耐久性问题，国内外尚未进行深入的研究．笔者通过对塑性混凝土宏观的溶蚀试验（CaO溶出过程试验）以及溶蚀前后微观的差热分析、扫描电镜和能谱分析，对塑性混凝土在有水渗漏下的耐久性问题作了深入的研究，并在此基础上，对塑性混凝土防渗墙和普通混凝土防渗墙的耐久性和使用年限作了相应的计算和评估．
Due to its low modulus of elasticity, plastic concrete cutoff wall can adapt to the deformation of sand-gravel foundation and has good crack resistance and impermeability. Therefore, as a new type of cut-off wall structure, preliminary results have been obtained in the project The promotion and application. However, the durability of plastic concrete, a new kind of wall material, has not been studied deeply at home and abroad. Through macroscopic corrosion test of plastic concrete (CaO dissolution process test) and microscopic differential thermal analysis (SEM) and scanning electron microscopy (SEM) and energy spectrum analysis before and after corrosion, the author made a deep research on the durability of plastic concrete under water leakage, On this basis, the durability and service life of plastic concrete cutoff wall and ordinary concrete cutoff wall are calculated and evaluated accordingly.
