摘要： 高压消防水幕对切断建筑间火灾蔓延的发展具有重要作用，可有效解决木结构建筑群普遍存在的建筑间防火间距不足的问题。为探究高压消防水幕在木结构建筑群中的适应性，选取典型穿斗式民居建筑为研究对象，采用FDS模拟分析高压消防水幕在不同布置形式及水雾粒径条件下的隔热效果，并结合全尺寸火灾试验验证结果的有效性。结果表明：不同工况条件下高压消防水幕均有较好的隔热效率，布置距离1.5 m、粒径300 μm工况下的隔热效果最好，约为60.92%；增设高压消防水幕可有效降低起火建筑的引燃距离，最大引燃距离降低约44%；基于火灾现场试验的隔热效率与模拟结果较为吻合，4 m和8 m处模拟值和试验值热辐射强度隔热效率相对误差均小于5%。

Abstract: The high-pressure fire water curtain plays an important role in cutting off the development of fire spread between buildings, and can solve the problem of insufficient fire seperation distance between buildings in wood structure building complexes effectively. In order to explore the adaptability of high-pressure fire water curtain in wood structure building complexes, this paper selects typical bucket-type residential buildings as the research object, and uses FDS to analyze the thermal insulation effect of high-pressure fire water curtain under different layout forms and water mist particle sizes, and combines the full-scale fire experiment to verify the effectiveness of the results. The results show that the high-pressure fire water curtain has good thermal insulation efficiency under different working conditions, and the thermal insulation efficiency is the best under the working condition of 1.5 m and 300 μm particle size, which is about 60.92%. The addition of high-pressure fire water curtain can effectively reduce the ignition distance of the burning building, and the maximμm ignition distance is reduced by about 44%. The thermal insulation efficiency based on the fire scene experiment is in good agreement with the simulation results, and the relative error of the thermal radiation intensity insulation efficiency of the simulated value and the experimental value at 4 m and 8 m is less than 5%.
