Based on an actual project , feng - shou - qu project in honghu city , hubei province , which is one of the biggest csbcs all over the country with a radius of 3 湖北洪沙线丰收渠桥涵工程主体由一半径3 . 30m 、斜跨9 . 334m与公路纵轴成45角的小桥组成，是全国波纹钢板小桥中跨径最大的一座桥涵。
3m and an oblique span of 9 . 334m , and bevels 45 with the axes of road , experimental study and mechanics analysis of csbcs are finished in this paper so as to resolve the first two problems above 本文针对其中的前两个问题，以该工程为背景，对波纹钢板桥涵进行了试验研究和力学性能分析。
On the basis of test under loading statically about static strain , opposite deformation to sedimentation of foundation on the actual project , further mechanics analysis of csbcs was done 通过现场静载试验，从结构的静态应变，相对变形，基础沉降等多个指标方面，对波纹钢板桥涵的力学性能进行了深入分析。
This paper presents a quick measuring method for bridge culvert structures ' ground bearing capacity and soil replacement method for ground strengthening when the bearing capacity can ' t meet the design requirements 摘要介绍公路工程建设中桥涵结构物基础承载力的快速测定方法以及在承载力不能满足设计要求情况下的换填处理。
And it is necessary for csbcs to have a great vitality and high possibility of wide application in future due to the properties of fast construction , elegant form and low price and otherwise 波纹钢板桥涵是一种新型结构形式，由一种新型建筑材料? ?波纹钢板拼装而成，具有施工便捷、造型优美、价格低廉诸多优异性能，有着极强的生命力和广阔的应用前景。
After choosing two bridges with pressure on signal board and making the research on it . it is clearly . seen that it is resulted from the both comparing actual data with these of design , we can find the difference between them 选出存在单板受力病害的两座典型桥涵，进行加载试验，得出该桥涵的挠度，对比实际挠度和设计要求挠度的差别，分析病害的程度。
Based on theory of water travel in catchment and reasoning formula , a new calculation model for flood flow design of culvert and small bridge in sichuan hilly area where is no runoff data is derived in the paper 因此，本文以著名的流域汇流公式为主，引入推理公式的思想，进行合理的概化导出了适合于四川丘陵地区无径流资料的中小桥涵设计洪水计算的新模型。
After investigating the cause the damage to the bridge , i think it includes two factors , one is singly board to afford the force . the other is one of evacuated base of face plates connecting with bridge . this problems lie in almost all high ways 对宣大高速公路小桥涵进行病害调查后，总结分类病害存在主要为单板受力和桥头搭板底脱空，这也几乎是所有高速公路都普遍存在的问题。
Based on the model of for the first time , the coupled model of csbcs and soil considering the interaction between them was established in this paper , in which csbcs was simplified into the arch structure with fixed support and problem of plane strain 本文按照耶梅里杨诺夫模型的思路，首次建立了波纹钢板桥涵和土的耦合作用模型，将波纹钢板桥涵简化为固支拱结构，按平面应变问题进行计算。
Contrast to other bridge and culvert , the advantages and disadvantages of csbcs are systematically analyzed , what more , the further research on the application of cspi ( corrugated steel pipe ) to both at home and abroad , construction technique thereof are made time 本文首先系统地分析了波纹钢板桥涵和其他桥涵相比所具有的优缺点，深入研究了波纹钢管的国内外的应用现状，以及其施工工艺。
