摘要：

为了探究微生物诱导碳酸钙沉淀(MICP)技术加固硅质海砂的耐候性能，对海水和淡水环境下加固后的试样进行干湿循环和酸溶液浸泡试验，测试了试样的表观变化、质量损失率和无侧限抗压强度（UCS），通过扫描电镜和X射线衍射分析试样劣化的内在机理. 结果表明，海水试样的抗干湿循环能力更强，60次干湿循环后，海水和淡水试样的质量损失率分别为3.60%和11.94%，UCS剩余率分别为38.44%和24.69%. 淡水试样的耐酸性能强于海水试样，60天不同pH酸溶液浸泡后，淡水和海水试样的质量损失率分别为0.44%~3.46%和0.51%~6.90%，UCS剩余率分别为51.22%~92.14%和26.47%~87.36%. 干湿循环没有改变试样内部碳酸钙晶体的形貌，试样强度的损失取决于砂颗粒间的胶结程度. 海水中的复杂离子促进了碳酸钙的均匀分布，使得海水试样具有更好的抗干湿循环性能. 酸溶液浸泡导致不同程度的碳酸钙晶体腐蚀，并破坏砂颗粒间的胶结作用. 淡水试样的碳酸钙生成质量相对更高，因此抵抗酸腐蚀能力更强.

Abstract:

Specimens treated in both seawater and freshwater environments were subjected to wet-dry cycling and acid solution immersion tests in order to analyze the weathering resistance of silica sea sand reinforced using microbially induced calcium carbonate precipitation (MICP). Apparent changes, mass-loss rate and unconfined compressive strength (UCS) were measured. The intrinsic mechanism of specimen deterioration was analyzed through scanning electron microscope and X-ray diffraction. Results showed that seawater specimens exhibited better resistance to dry-wet cycles than freshwater specimens, with mass-loss rates of 3.60% and 11.94% after 60 cycles, and the UCS residual ratios were 38.44% and 24.69%, respectively. Freshwater specimens demonstrated greater acid resistance than seawater specimens. The mass-loss rates of freshwater and seawater specimens were 0.44%-3.46% and 0.51%-6.90%, respectively, with UCS residual ratios being 51.22%-92.14% and 26.47%-87.36% after 60 days of immersion in acid solutions of varying pH. Dry-wet cycles did not affect the morphology of calcium carbonate crystals inside the specimens. The strength-loss was mainly due to the degree of cementation between sand particles. The complex ions in seawater promote the uniform distribution of calcium carbonate, resulting in better resistance to dry-wet cycles in seawater specimens. Immersion in acid solutions leads to varying degrees of corrosion of calcium carbonate crystals, damaging the cementation between sand particles. Since freshwater specimens contain a relatively higher mass of calcium carbonate, their ability to resist acid corrosion is stronger.
