摘　　要：建筑墙体在隔绝噪声中起着关键作用,由于各种建筑设备管线在墙体上开洞较多,在已知期望隔声量的条件下,如何确定墙体上缝隙最大面积成为一项重要的课题.采用免疫算法建立了隔声计算模型,将预期的隔声量定义成目标函数,单层墙的厚度、面密度与杨氏模量定义成约束变量.运用Matlab编程实现了目标函数全局最大值的求解,从而确定达到该隔声量的墙体材料、厚度和构造大样.Building wall plays a key role in the isolated noise;as a lot of open holes in the wall for construction equipment lines;it is an important issue to determine the maximum area of wall cracks under the condition of expected sound insulation quantity.The calculation model is made by immune algorithm;the expected sound insulation quantity is defined as objective function;the areal density,thickness and Young＇s modulus of monolayer wall are defined as bounded variable.The global maximum of objective function is obtained by the Matlab program.Therefore,the materials,thickness of wall and construction details for sound insulation requirerment are determined.
