8度抗震设防地区综合管廊的结构设计
|
摘要
在松原市某8度抗震设防地区综合管廊项目设计中,选用"田"字型管廊结构,将管线管廊和雨水箱涵相结合,满足入廊管线和工艺排水的要求,同时节约了工程施工造价。将管廊变形缝橡胶止水带不锈钢板部分采用铆钉连接,橡胶部分采用热熔连接,解决了止水带施工搭接不严的难题。对8度区的管廊进行了承载能力极限状态、正常使用极限状态和抗震设计,抗震计算采用了反应位移法,结果表明,管廊外框架的配筋由正常使用极限状态荷载组合的效应设计值控制,中隔墙和中隔板的配筋由地震作用荷载组合的效应值控制。?850的SMW水泥土搅拌墙在管廊基坑的应用,成为密实砂质土层地区首例成功实施的案例。
In order to meet the requirement of corridor pipe,drainage process,and saving construction cost,the "田"shape structure form was reasonable applied to utility tunnel which combined with pipe utility tunnel and rainwater box culvert in Songyuan. The problem of poor construction of the waterproof strip in deformation joint was solved by using riveting of stainless steel plate and hot-melting connection of rubber. The design of bearing capacity limit state,normal service limit state and earthquake resistance were applied to utility tunnel with 8-degree intensity,and the response displacement method was applied in the seismic calculation. The calculation results showed that the reinforcement of outer frame was determined by the effect of load combination of normal service limit state,but the reinforcement of mid-partition wall and mid-partition plate was determined by the effect of load combination of earthquake action. The ?850 SMW cement-soil wall was successfully used in excavations of utility tunnel,which was the first example in compacting sandy soil.
