摘　　要：介绍了复杂环境下对1座38m高倒锥形水塔的定向控制爆破拆除,论述了倒锥形水塔爆破拆除的爆破设计和爆破切口参数。通过精心组织施工、采取有效的安全防护,水塔起爆后完全按照设计倾倒方向倒塌,爆破产生的飞石和二次飞溅控制较好,未产生飞散危害,达到预期的爆破效果。爆破实践表明,对小直径建(构)筑物的爆破拆除,适当提高切口高度对其顺利倾倒是有利的,值得类似工程爆破中参考。The demolition of a 38m high reverse cone-shape water-tower under complicated circumstances by controlled blasting is introduced. The blasting scheme, blasting design, blasting cutting parameters, and the safety precautions are discussed. The desired blasting result is attained. The practice shows that the higher gap is beneficial to guarantee the structures with smaller diameter collapse effectively in the similar engineering.
