作者 栾昌花 《中国公路》 2012年第14期112-115,共4页
招标控制价即招标人在招标过程中能够接受的最高交易价格,投标人的投标报价高于招标控制价的,其投标应作废标处理。招标控制价设置的目的是将相关工程的招标价格限定在合理的范围内,用于控制高估冒算,串通抬价,虚增投资。

A caisson foundation is applied to the north anchorage of Taizhou Yangtze River Highway Bridge of which the initial caisson sinking requires dewatering. Since the caisson foundation is quite close to nearby buildings, a system control model is established with source (sink) distribution and intensity being the object function, minimum requirements of settlement and deformation of surroundings caused by dewatering and dynamic water levels during different working procedures being constraints, and the design parameter of pumping wells being the variable,so as to lower the jeopardizing of surrounding buildings, which provides a new method for active control over settlement during dewatering. Such a method of dewatering based on system control model should be of significance for similar projects involving dewatering. 展开更多
