预压的 meaning in Chinese
prepressing
Examples
- An oil tank ' s foundation was consolidated by water filling preloading method
摘要采用油罐充水预压的方法加固某油罐地基。 - With resonable calculating model and dynamic analysis method , the construction control elevation can be decided and so the precompression difficulty of support can be solved in the construction of large - span arched bridge
采用精确的计算模型和动态分析技术，一次性给出施工控制标高，解决了大跨度拱桥有支架施工中支架需要预压的问题。 - The cause of vacuum degree formation under groundwater table is discussed in the paper . the testing results show that vacuum degree above the groundwater table is produced directly by pumping air , and that vacuum degree below groundwater table is produced mainly by dewatering and by escaping of sealed air from the end of flexible pipe . based on the bernoulli equation , the limit lowering of groundwater table is analyzed , which is about 5 ~ 7m . the effective influence depth of vacuum preloading has relationship with pvds depth and can be more than 10m
对地下水位线以下的真空度成因进行了分析，结果表明，地下水位线以下测到的真空度是由于测试软管中水位下降或部分封存气体从软管末端逃逸引起的，与地下水位线以上的真空度由抽气直接形成在成因上存在不同；根据伯努俐方程，对地下水位下降的极限深度进行了分析，得出真空预压中地下水位的极限下降深度为5 7m ；对有效影响深度的分析结果表明，真空预压的有效影响深度与塑料排水板的打设深度具备一定关系，有效影响深度可以超过10m 。 - In order to search after its applying to expressway roadbed improvement , this paper studied consolidation characteristic and distortion law hi soft soil under positive and negative action , introducing parse explain and numerical calculation theory . additionally , based on locale experimentation , the design and construction method of vhlcp was implemented and its reinforce effect and economical character was estimated . testing indicated that the groundwork ' s intensity have increased 97 % , silt soil have vanished and outlay have saved 39 %
根据现场试验，确定了适合于高速公路工程要求的真空堆载联合预压的设计和施工方法，并分析评价了其加固效果和经济性，试验表明：应用真空堆载联合预压后，地基强度平均提高了97 ，地基中淤泥质土已消失；与粉喷桩加固地基相比，节省经费39 。 - The mechanics of vacuum preloading was discussed by contrast of vacuum preloading and heaped preloading . the factors affecting the result of vacuum preloading for ground consolidation were as follows : the geological conditions of site , the intensity of vacuum pumping , the condition of underground water and installation of vertical drainage line . through analysis of these factors , some conceptions and design principles were proposed for vacuum preloading
在此基础上，通过堆载预压与真空预压的对比阐述了真空预压加固地基机理，分析了影响真空预压加固地基最终加固效果的各个因素：场地地质条件、抽真空作用强度、地下水赋存情况及竖向排水体的设置等。
