抚顺××厂３＃万ｍ３储油罐自１９９０年以来，罐体基础持续产生不均匀沉降。围绕该储油罐，通过高压定喷施工工艺，构筑定喷桩，地下防渗连续墙，在墙体内侧对罐体地基进行冲积层及基岩的直、斜孔注浆，用水泥浆液充填、胶结地基中的空化、裂隙，提高了地基强度，对减缓罐体的不均匀沉降，取得了显著成效。 Fushun × × plant 3 million m3 oil storage tanks since 1990, the tank base continued to produce uneven settlement. Around the oil storage tank, through the high-pressure and fixed spray construction process, the fixed jet piles and the underground impervious continuous wall are constructed. In the inside of the wall, the tank foundation is subjected to alluvial and basement rock straight and oblique hole grouting and filled with cement slurry. The cavitation and fissures in the cemented ground improved the strength of the foundation and slowed the uneven settlement of the tank, achieving remarkable results.
