( 5 ) based upon numerical simulation , the effect of initial value and measure random error on back - analysis is discussed , and the first parameter and the second parameter of two - parameter model of the experimental field is identified using the experimental data ( 5 )通过数值模拟，分析了初值及测量结果随机误差对反分析结果的影响，并利用试验数据，识别出试验场地双参数地基模型的第一参数与第二参数。
The cast basalt tiles may be used in all kinds of ways . such as : the liner of coal bunker of power station , the lining of dust cyclone , the liner of chemical storage tank and warehouse for corrosion material , the floor material for chemical plants and lowfriction vehicle testing surface etc 玄武岩铸石板主要用于衬砌火电厂煤仓，各种规格旋风除尘器、旋流器、铺设各类化工厂地面，汽车刹车试验场地面等，也可用于衬砌酸洗槽或储存腐蚀性物品的贮存室。
The static loading test for three group of testing piles of jiading power plant secend stage project are analyzed and studied in this thesis , and the practical applying of high - accurate data collector , technique of waterproof insulation and testing technique of burying in the body of pile are introduced also . the vertical and horizontal loading features of three group of piles of different kind and constructing technique in different earth layer at the pile point are analyzed and compared and summed up with basic integro - differential equation calculating the pile earth system load transmit , transforming principle of stress - deforming and pile body rating of burying electric measuring element . changing law of stress , and changing law of pile body shifting and bending for different testing piles under vertical and horizontal load are showed so that the loading features of soil layer and pile at testing spot , reliable design data for pile type and base for scientific construction technique are provided 本文仅就嘉定电厂二期工程中的三根试验桩的静载试验进行了分析和研究，利用桩土体系荷载传递分析计算的基本微分方程及应力-应变转换原理，结合预埋电测元件的桩身率定，对三组不同种类、不同施工工艺、不同持力层中的桩的竖直、水平承载特性进行了分析、比较和归纳，通过大量、全面的实测数据，经过整理、转换和推演，揭示了不同试验桩在竖直、水平荷载作用下的应力变化规律和桩身变位、挠曲变化规律，最终提供试验场地土层和桩的承载特性，为该工程合理设计桩型提供了可靠的设计参数，为确定科学的施工工艺提供了有力的依据。
Traditional load test is generally accepted as a most directly and reliable method for determining the bearing capacity of piles . because the method need special reaction system , it will take more time and money and require high condition for test field . so it cannot be done randomly and widely , and cannot be done under hardly conditions 传统静载试验是公认的确定单桩承载力最直观、最可靠的方法，但由于必需专门的反力系统，试验费时、费力、费用高昂且对试验场地有着极高的要求，也因此不可能做到随机抽检及大量普查；特别是在某些恶劣的条件下，由于空间的限制甚至不可能进行静载试验。
The software was developed by visual basic 6 . 0 and borland c + + 5 . 0 , which have high versatility , adaptability and extension . this system has been used to load - test automobile on the testing field which was provided by a automaker company ' s technology center , the test result has proved that this design method was correct and applied 该测试系统以重庆某汽车股份有限公司技术中心提供的汽车和试验场地进行了大量的道路实测试验，以实践效果证明了上述设计方法和技术的正确性和实用性，达到了预期设计的性能指标，和国外同类型产品比较大大节省了成本，取得了良好的经济效益。
