[0059] 说明:工程师的这一个思维过程通常是在设计过程的最前面,本发明安排在S4-1 步骤进行区间化设计,主要是因为前述过程都是可以跨越区间的预处理过程,集中连贯处理更利于程序上的实现与效率上的优化,但数据的预处理过程也是可以分区间进行的,因此与工程师的设计过程是不冲突的; [0059] Description: This is a thought process engineers usually at the top of the design process, the present invention is arranged in a section for design step S4-1, the process is mainly due to the pretreatment process can be cross section, coherent concentration process more conducive to the realization of optimization and efficiency of the program, but also pre-process data that can be made between partitions, and engineers design process is no conflict;

[0060] 步骤S4-2 :对截取的拟合坡度线,分别从区间起点向后,尾点向前进行两次的坡度调整遍历,对其中坡度值大于规范要求的坡段,以给定的最大允可坡度配置计算确立下一采样点的允可高程值并进行顺延调整; [0060] Step S4-2: the slope of the fitted line, taken, respectively, from the starting point back section, tail points forward slope adjustment traversed twice, wherein the slope of the slope value is greater than Compliant section, a given Yunke established maximum gradient location calculation Yunke elevation value of the next sample point is adjusted and extended;

[0061] 步骤S4-3 :顺延检索过程中,对前述标注的山尖点进行人字坡或单坡排水设计; 对标注的高地点进行人字坡或拱坡排水设计;当高地的中央平地距离小于一定距离时(如〈3KM),可视为平顶高山,从中剔出高地点,并作为标注补充一个山尖点,按大山模式进行处理,设置人字坡或单斜坡;高地中央平地距离超出给定距离阈值时,高地两侧的大坡度线可以通过双向顺延进行自动调整,无须额外处理。 [0061] Step S4-3: extended retrieval process, the labels will be the point Shanjian word or a single grade slope drainage design; locations denoted high slope or herringbone design Arch drainage slope; if central flat highlands when the distance is less than a certain distance (such as <3KM), can be regarded as flat-topped mountains, excised from high places, and as a supplement jian point mark, according to the mountain mode processing, set the herringbone slope or single slope; the central highland plains when the distance exceeds a given distance threshold, large slope on both sides of the line can be automatically adjusted by the heights bidirectional extended without additional processing.

[0062] 所述步骤S4中对区间内的群山、大山、高地标注区域进行人字坡或单斜坡排水设计的方法,采用最优试测的方法实现如下: [0062] Step S4, the inner section of the mountains, mountain, highland area labeling method or a single word ramp slope drainage design, optimal use of the test method to achieve the following test:

[0063] 如图5所示,假定A、B两点分别为大山入口与出口变坡点,相距里程为IX,两点高程差为Λ H,变坡点可能是区间内的任何一点0,为了方便,将AB区间分为10份进行切割定位,假定变坡点的位置处于m/ΙΟ处,m为大于0小于10的正数。 [0063] As shown in FIG 5, it is assumed A, B are two mountains PVI inlet and the outlet, for the mileage distance IX, two elevation difference Λ H, PVI can be any within the range 1.0, for convenience, the AB interval is divided into 10 parts of cut positioning, PVI assumed position is at m / ΙΟ at, m is a positive number greater than 0 and less than 10.

[0064] 设两段坡线的斜率绝对值分别为K1、K2,则按照几何逻辑关系,有如下的推理公式: [0064] The slope of the line located two slope absolute values ​​as K1, K2, according to the geometric logic, reasoning following equation:

Figure CN104462692AD00081

[0068] 上面的公式准确了描述了m、KU Κ2之间的数理关系,要确立区间坡线,实质就是要确立其中两个参数条件即可,第三个参数就自然可以通过该公式计算出来。 [0068] The above equation accurately describes the mathematical relationship between m, KU Κ2, to establish the slope of the line section, wherein the substance is to establish two parameter conditions can, naturally the third parameter can be calculated by the formula . 结合工程设计我们来分析这三个参数的作用:m确立的是山中变坡点的设置位置,通常隧道施工是双向进行的,为了保障施工周期与施工方便,自然是两段边坡能够等长为好,所以m越处于中间点位置越好。 We combine engineering design to analyze the role of these three parameters: m-established position is set in the mountains PVI, usually two-way tunnel construction is carried out, in order to protect the construction period and facilitate the construction, natural slope can be as long as two as well, so that m is in the intermediate position as possible. KU K2有两重作用,一是弥补大山两侧的出入口落差过渡;二是考虑排水。 KU K2 has two functions, one to make up the mountains on both sides of the entrance gap transition; the second is to consider drainage. 如果仅就排水,考虑动力性能,自然是坡度越小越好,3%。 If only for drainage, consider the dynamic performance, the smaller the better natural slope is 3%. 的坡就足够了。 The slope is enough. 此外,两边坡度一致既能够保持良好的动力性能,也能简化设计施工的难度。 In addition, both sides agreed to maintain the slope of a good dynamic performance, can simplify the difficulty of design and construction.

[0069] 综上所述,可以列出确立上述参数的三个最优条件如下: Optimal conditions for three [0069] In summary, the above parameters can be listed established as follows:

Figure CN104462692AD00082

[0071] 实施方法:按2〈K1,K2〈MaxSlope按递进坡度0. 5进行逐个给定,计算出相应的m 值后。 [0071] The procedure: press 2 <K1, K2 <MaxSlope-by progressive slope given by 0.5 to calculate the corresponding value of m. 若得到的m值小于O或大于10,此时意味着该给定坡度设计不出来山中的人字坡,设坡无效可以跳过,继续试探其它的组合参数。 If the resulting value of m is less than or greater than O 10, at this time means that the slope of the given design does not come out of the word mountain slope, the slope is provided to skip invalid, continue to test other combinations of parameters.

[0072] 对计算出来的有效人字坡,还需要进行如下的检测才能最终确立: [0072] effective herringbone slope calculated, but also need the following final testing to establish:

[0073] ①两段坡的长度要求满足线路对坡长的限制条件; [0073] ① two longitudinal slope of the line in claim slope length constraints is satisfied;

[0074] ②变坡点要在地面线下20M以下的深度,否则隧道埋深过浅,容易造成安全事故。 [0074] ② PVI to the depth of 20M or less in line ground, otherwise the tunnel depth is too shallow, easily lead to accidents.

[0075] 对判断有效的所有人字坡进行比较,是基于三个层面进行的,优先M - 5,其次K1+K2 - 6,再次Kl = K2进行选优判断,得到最优的KU K2、m参数后确立人字坡。 [0075] The determination of the effective slope of all words compared, is based on three levels, the priority M - 5, followed by K1 + K2 - 6, again Kl = K2 Selecting the optimum determination of optimal KU K2, after establishing the slope m word parameters.
