- the traditional strain measurement method uses strain gauges to measure strain, which is generally within a range of several centimeters.
- Macroscopic strain also uses the definition of strain. The ratio of elongation or compression to length within a given range is used as the strain quantity. The distance between two points is measured, as well as the relative displacement over a period of time. The relative displacement is divided by the original distance.

土体参数包括温度。管道参数包括管道应变。管道应变是指埋地管道在外力作用下的局部的相对变形的程度。埋地管道在温度影响下会产生应变。温度不同，埋地管道因温度产生的应变也不同。在本申请实施例中仅考虑长期因素对埋地管道的影响，不考虑短期因素对埋地管道的影响，即不考虑因温度而产生的管道应变，因此需要根据温度修正通过应变传感器采集的管道应变。处理器通过对管道应变进行微分可以确定埋地管道的应变变化率。
处理器根据修正后的土体参数、土体对埋地管道的作用力或埋地管道的应变变化率发送对应的报警信号至显示设备。报警信号分为一级报警信号、二级报警信号和三级报警信号。这样，可以满足对埋地管道在不同阶段的安全进行监测的需求，提高预警的准确度。
通过上述技术方案，实时获取多个传感器发送的埋地管道的环境参数、土体参数和管道参数，并通过环境参数修正土体参数，以得到修正后的土体参数，从而能够根据修正后的土体参数确定土体对埋地管道的作用力，根据管道参数确定埋地管道的应变变化率。并进一步结合修正后的土体参数、土体对埋地管道的作用力或埋地管道的应变变化率发送对应的报警信号至显示设备。本申请基于埋地管道的环境数据、土体数据和管道数据，能够确定土体对埋地管道的作用力及土体与埋地管道在相互作用下的演变规律，实现对埋地管道安全进行监控的目的，并提高预警预报的可靠性与准确性。
在本申请实施例中，环境参数可以包括降雨量，土体参数可以包括含水量和温度，S302、通过环境参数修正土体参数，以得到修正后的土体参数可以包括：
S3020、根据降雨量确定土体的含水量的预测值，具体地：土体的含水量与降雨量、土体坡度以及植被覆盖相关，首先测量当地降雨量与时间的分布曲线，土壤中的含水量随时间变化情况，通过实测值预测以后时间的降雨量与含水量的变化情况，基于该变化情况，能够根据降雨量确定土体的含水量的预测值。

动态参数，那么，能够根据含水量的预测值和温度确定土体力学性能参数。
S305、根据修正后的土体参数、土体对埋地管道的作用力或埋地管道的应变变化率发送对应的报警信号至显示设备可以包括：
S3050、在土体力学性能参数小于第一设定值的情况下，发送三级报警信号。
具体地，报警信号分为一级报警信号、二级报警信号和三级报警信号。一级报警信号是在埋地管道临灾时发送的临灾报警信号。二级报警信号是在土体发生移动时发送的致灾报警信号。三级报警信号是进行长周期趋势预警时发送的趋势报警信号。处理器可以根据修正后的土体参数确定是否发送三级报警信号。通过降雨传感器，处理器可以获取埋地管道周边的降雨量，并建立降雨量和时间的关系，从而预测土体的含水量在一定时间内的变化趋势。并且，处理器可以预先测定土体在不同的含水量和温度下的土体力学性能参数。这样，在监控管土耦合作用的过程中，根据土体的含水量的预测值及土体的温度可以确定土体力学性能参数。进一步地，根据实际情况可以预先设定第一设定值。第一设定值是用于判断土体是否失稳的临界值。在大于或等于第一设定值的情况下，土体稳定，发生地质灾害的可能性较低，因此不需要发送报警信号。在小于第一设定值的情况下，土体发生滑动的可能性较高，需要发送三级报警信号以进行预警。通过实时监测降雨量，并实时分析降雨强度、降雨时间和降雨量，预测土壤性质可能发生的变化，从而能够对地质灾害进行提前预警。
在本申请实施例中，多个传感器可以包括降雨传感器、水分传感器和温度传感器，根据降雨量确定土体的含水量的预测值可以包括：
通过降雨传感器采集埋地管道周边环境的降雨量；
通过水分传感器采集土体的含水量；
根据土体的含水量和降雨量确定土体的含水量预测值；
根据含水量的预测值和温度确定土体力学性能参数包括：
通过温度传感器采集土体的温度；
根据含水量的预测值和温度确定土体力学性能参数。
具体地，处理器可以获取多个传感器采集的数据，从而确定土体力学性能参数。在本申请实施例中，多个传感器包括降雨传感器、水分传感器和温度传感器。降雨传感器用于采集埋地管道周边环境的降雨量。水分传感器用于采集埋地管道周边土体的含水量。温度传感器用于采集埋地管道周边土体的温度。处理器可以获取埋地管道周边环境的降雨量，并建立降雨量和时间的关系，从而预测土体的含水量在一定时间内的变化趋势。并且，处理器可以预先测定土体在不同的含水量和温度下的土体力学性能参数。这样，在监控管土耦合作用的过程中，根据土体的含水量的预测值及土体的温度可以确定土体力学性能参数。
在本申请实施例中，修正后的土体参数还可以包括深部位移和表部位移，S303、根据修正后的土体参数确定土体对埋地管道的作用力可以包括：
S3030、根据深部位移和表部位移确定土体的体积；具体地：根据深部位移可以确定滑动的深度、表部位移确定滑动的面积(投影范围)，通过面积和深度的乘积就可以得到土体的体积。
S3031、根据土体的体积和土体力学性能参数确定土体对埋地管道的作用力；具体地：土体的体积乘以密度就是土体的重量，土体的重量与滑动角度的乘积就是对管道的作用力。考虑土体的压缩强度等土体力学性能就可以获得对管道的推挤作用力。
S305、根据修正后的土体参数、土体对埋地管道的作用力或埋地管道的应变变化率发送对应的报警信号至显示设备可以包括：
S3051、在土体对埋地管道的作用力大于第二设定值的情况下，发送二级报警信号。
具体地，处理器可以根据修正后的土体参数确定土体对埋地管道的作用力。修正后
的土体参数还包括深部位移和表部位移。通过深部位移传感器可以获取土体的深部位移。通过表部位移传感器可以获取土体的表部位移。此外，根据土体的深部位移可以得到对埋地管道施加作用力的土体的厚度。
由于表部位移传感器采集的数据存在误差，因此需要对表部位移传感器采集的数据进行修正。在埋地管道周边的土体上可以设置图像采集设备。通过图像采集设备实时采集土体的图像数据，通过与前期采集的基准图像进行比对，以监测土体的表部位移。根据通过图像采集设备获取的土体的图像数据，处理器可以修正表部位移。由此，处理器可以根据深部位移和表部位移确定对埋地管道施加作用力的土体的体积。结合土体的体积和土体力学性能参数，处理器可以确定土体对埋地管道的作用力。
在监测过程中，深部位移传感器和表部位移传感器采集的数据存在偏差，导致处理器确定的土体对埋地管道的作用力存在误差，因此，可以通过土压力传感器获取土体对埋地管道的压力，以对根据土体力学性能参数、深部位移和表部位移确定的土体对埋地管道的压力进行修正。在一个示例中，在埋地管道同一截面上等间隔地安装四个土压力传感器，以监测埋地管道多个方向的土体压力。通过土压力传感器采集土体对埋地管道的作用力，可以修正根据土体力学性能参数、深部位移和表部位移确定的土体对埋地管道的压力。
处理器可以预设第二设定值，第二设定值需要根据实际情况设定。第二设定值是指土体对埋地管道的压力足以使埋地管道发生位移的临界值。在土体对埋地管道的作用力大于第二设定值的情况下，埋地管道发生位移，处理器需要发送二级报警信号。
进一步地，处理器通过单位采样时间内深部位移和表部位移可以确定不同位置的土体位移速度，具体地：土体位移速度就是两次采样间隔之间的位移除以时间间隔，土体是非均质的，因此各个位置处的移动速度一般不一致，需要分别计算不同位置的土体移动速度。
深部测斜管是一种用于监测土体内部水平位移的测量管。由于不同深度的土体位移速度存在偏差，可以在埋地管道上设置深部测斜管，以监测土体的形变，并确定发生位移的土体的位置，具体地：通过钻孔将测斜管垂直安装在土体中，从而测量深度方向上的位移，通过不同位置位移的土边点来确定发生滑动的深度。一般是深部没有位移的为基岩，基岩上方与表部一起发生位移的深度就是滑动面的深度。根据土体位移速度和通过深部测斜管确定的土体不均匀形变的位置，可以确定埋地管道受剪切的截面，具体地：深部测斜管可以测到不同深度的土体形变情况，多个位置的表部、深部位移的速度不一致，在滑动体内的位移量大，边缘位置速度慢，滑动体外没有位移，因此通过多个位移监测点的位移变化速度可以插值拟合速度曲线，速度为0的位置为静止点，插值获得的加速度为零的点为剪切面。通过确定埋地管道受剪切的截面，处理器可以确定土体对埋地管道作用的范围，其中，两个受剪切位置之间的管道长度就是土体对埋地管道作用的范围。
通过深部位移和表部位移确定土体对埋地管道的作用力、作用范围，并通过土压力传感器采集的土体压力数据修正通过深部位移和表部位移确定土体对埋地管道的作用力，可以实时监测埋地管道的受力状况,具体地：管道深部位移和表部位移可以确定滑动的土体的体积，体积与密度的乘积得到土体的质量，土体质量和滑动角度的乘积就是坡面方向的推挤作用力。这个推挤作用力与直接测量的土压力数据进行交互验证，就可以修正滑动土体变化之后的管土作用力。
在本申请实施例中，多个传感器可以包括深部位移传感器和表部位移传感器，根据深部位移和表部位移确定土体的体积可以包括：
通过深部位移传感器采集深部位移；
通过表部位移传感器采集表部位移；
根据深部位移和表部位移确定土体的体积。
具体地，处理器可以获取多个传感器采集的数据，进而确定对埋地管道施加作用力的土体的体积。多个传感器包括深部位移传感器和表部位移传感器。通过深部位移传感器可以获取埋地管道周边土体的深部位移。通过表部位移传感器可以获取埋地管道周边土体的表部位移。此外，根据土体的深部位移可以得到对埋地管道施加作用力的土体的厚度。由此，处理器可以确定对埋地管道施加作用力的土体的体积。通过深部位移传感器和表部位移传感器采集的深部位移和表部位移确定对埋地管道施加作用力的土体的体积，以便处理器确定土体对埋地管道施加的作用力。
在本申请实施例中，管道参数可以包括管道应变，多个传感器可以包括应变传感器，S301、实时获取多个传感器发送的埋地管道的环境参数、土体参数和管道参数可以包括：
通过应变传感器获取埋地管道的管道应变；
S304、根据管道参数确定埋地管道的应变变化率可以包括：
将管道应变进行微分，以得到埋地管道的应变变化率；
S305、根据修正后的土体参数、土体对埋地管道的作用力或埋地管道的应变变化率发送对应的报警信号至显示设备可以包括：
在埋地管道的应变变化率在第一预设范围内的情况下，发送一级报警信号；
在埋地管道的应变变化率在第二预设范围内的情况下，发送二级报警信号；
在埋地管道的应变变化率在第三预设范围内的情况下，发送三级报警信号。
具体地，管道参数包括管道应变。处理器可以通过应变传感器获取埋地管道的管道应变。埋地管道在温度影响下会产生应变。温度不同，埋地管道因温度产生的应变也不同。在本申请实施例中仅考虑长期因素对埋地管道的影响，不考虑短期因素对埋地管道的影响，即因温度而产生的管道应变，因此需要根据温度修正通过应变传感器采集的管道应变。在一个示例中，埋地管道在温度变化的情况下，埋地管道的两点之间按照管道的膨胀系数发生变形。处理器可以同时监测埋地管道上多个截面的温度、应变和位移，通过确定实际位移与理论位移的差值消除因温度影响而产生的埋地管道的管道应变，其中，实际位移就是管道多个截面上位移计测量获得的位移，理论位移就是通过算法预测的位移，算法是基于管土推力作用计算获得的值。
第一预设范围是埋地管道断裂的可能性较高的应变变化率的范围。第二预设范围是埋地管道受土体施加的作用力影响、发生严重变形的应变变化率的范围。第三预设范围是指管道发生明显变形的应变变化率的范围。在根据温度修正通过应变传感器采集的管道应变的情况下，处理器可以根据埋地管道的应变变化率发送报警信号。多个传感器包括应变传感器。通过应变传感器可以采集埋地管道的管道应变。管道应变是指埋地管道在外力作用下的局部的相对变形的程度。处理器需要根据温度修正管道应变。处理器对管道应变进行微分，可以得到埋地管道的应变速率。对应变速率进行微分，可以确定埋地管道的应变变化率。处理器根据埋地管道的应变变化率可以发送不同级别的报警信号。在一个示例中，假设第一预设范围为大于或等于0.8，第二预设范围为大于或等于0.5且小于0.8，第三预设范围为大于或等于0.2且小于0.5。在埋地管道的应变变化率大于或等于0.8的情况下，处理器发送一级报警信号。在埋地管道的应变变化率大于或等于0.5且小于0.8的情况下，处理器发送二级报警信号。在埋地管道的应变变化率大于或等于0.2且小于0.5的情况下，处理器发送三级报警信号。根据埋地管道的应变变化率发送报警信号，可以实现通过监测埋地管道本身的状态以确定不同的报警信号的目的。
在本申请实施例中，管道参数还可以包括管道位移，多个传感器还可以包括管体位移传感器，该方法还可以包括：
通过管体位移传感器获取埋地管道的多个点的管道位移；
根据多个点中的相邻两个点的管道位移的相对值确定埋地管道的宏观应变趋势；
根据埋地管道的目标点的管道应变的方向与宏观应变趋势确定重要截面的位置；
将重要截面的位置发送至显示设备。
其中，目标点是需要分析的点，通过分析目标点上下游2个点的位移方向可以确定压缩或者拉升。如果是位移绝对值变大，则为拉升，位移绝对值变小，则为压缩。
宏观应变趋势的具体解释如下：
传统的应变测量方式是采用应变片测量，测量的一般是几厘米范围内的应变。宏观应变也是利用应变的定义，给定范围内的伸长或者压缩与长度的比例作为应变量，测量2个点之间的距离，以及过一段时间的相对位移，相对位移除以原来的距离就是宏观应变量。该方法可以测量任意长度，比如100m、1km、10km管段长度的宏观应变趋势。管段的实际长度可以采用内检测数据进行确定。
具体地，处理器可以根据埋地管道的管道位移确定埋地管道的宏观应变。管道参数还包括管道位移。管道位移是埋地管道在外界因素作用下发生的位移。通过在埋地管道上设置多个管体位移传感器，处理器可以确定埋地管道上多个点的位移值。管体位移传感器包括但不限于基于微机电系统的加速度传感器、普通振动类加速度传感器、普通振动类速度传感器和位移传感器。在一个示例中，通过三轴加速度传感器监测埋地管道的管道位移。根据相邻两点之间埋地管道位移的相对值，处理器可以进一步判断埋地管道的宏观应变。在埋地管道上目标点的应变方向与宏观应变趋势一致的情况下，判断埋地管道形变均匀。目标点是指埋地管道上发生管道应变的点。在埋地管道上目标点的应变方向与宏观应变不一致，即宏观应变拉伸、局部应变压缩，或者宏观应变压缩、局部应变拉伸，则将目标点所在的截面定义为重要截面，且处理器可以确定该重要截面断裂的可能性较高，由此处理器在发送报警信号时可以将该重要截面的位置发送至显示设备。同时，在埋地管道发生侧向位移的情况下，处理器可以通过管体位移传感器确定埋地管道的形变，辅助埋地管道的管道应变监测结果判断管道的安全状况，以提高监测埋地管道安全的准确性。
在本申请实施例中，多个传感器可以包括布里渊光纤传感器，该方法还可以包括：
通过布里渊光纤传感器确定埋地管道的伴行光缆应变的位置；
在伴行光缆应变的位置的数量超过预设数量的情况下，发送二级报警信号。
具体地，处理器可以通过布里渊光纤传感器监测埋地管道的伴行光缆应变，以确定埋地管道的伴行光缆应变的位置。布里渊光纤传感器是基于光纤中的布里渊散射对应变的敏感性而进行长距离的光纤应变监测的传感器。通过布里渊光纤传感器可以确定埋地管道的伴行光缆应变的位置，从而确定土体的形变位置。由于埋地管道自身的材质，使得通过管道应变确定土体的形变位置这一过程存在误差。因此，通过布里渊光纤传感器监测伴行光缆的应变，可以提高确定土体形变位置的准确性。在一个示例中，在伴行光缆发生微应变的位置的数量超过50个的情况下，处理器可以发送二级报警信号。其中，微应变的范围需要根据实际情况确定。
此外，由于深部位移传感器和表部位移传感器的数量有限，在监测土体对埋地管道的作用范围的过程中具有局限性，因此，处理器可以通过布里渊光纤传感器确定埋地管道的伴行光缆的应变的位置，并根据伴行光缆的应变的位置确定土体的形变位置，进而确定土体对埋地管道的作用范围。通过监测埋地管道的伴行光缆应变的位置，并基于伴行光缆应变的位置的数量确定报警信号，能够提高对埋地管道监测的全面性和准确性。
在本申请实施例中，环境参数还可以包括次声波信号和震动信号，多个传感器可以包括次声波传感器和地震传感器，该方法还可以包括：
通过次声波传感器检测次声波信号；
通过地震传感器检测震动信号；
在检测到次声波信号和震动信号的情况下，发送三级报警信号。
具体地，处理器可以通过次声波传感器和地震传感器监测次声波信号和震动信号，并根据次声波信号和震动信号确定报警信号。在次声波传感器监测到次声波信号且地震传感器监测到震动信号的情况下，存在发生地质灾害的危险，因此需要发送三级报警信号，以进行预警。通过监测埋地管道周边的次声波信号和震动信号，可以降低埋地管道因地质灾害受损的概率。
图4示意性示出了根据本申请一具体实施例的一种用于监控管土耦合作用的方法的流程图。如图4所示，在一个具体实施例中，长周期诱发因素监测预测是指根据埋地管道周边环境的环境参数预测埋地管道安全的监测方式。短周期致灾因素土体参数监测预报是指根据埋地管道周边土体的土体参数预测埋地管道安全的监测方式。临灾管体监测预警是指根据埋地管道本身的状态预测埋地管道安全的监测方式。本申请实施例可以在土体上设置一个雨量测站及降雨传感器，以进行降雨量监测。雨量测站能对单位时间降雨量、降雨总量进行实时监测，并将监测数据传输至处理器。降雨量每超过10毫米，雨量测站可以自动发送一次数据。并且，还可以在土体上同时设置次声波传感器和地震传感器，以监测土体移动的信号。
本申请实施例采用三级报警信号，三级报警信号包括一级报警信号、二级报警信号和三级报警信号。通过降雨传感器和水分传感器，可以实时修正土体力学性能参数。根据降雨量可以确定土体含水量和土体力学性能参数的预测量。在预测一小时后土壤含水率将达到饱和且在现有的坡度条件可能发生到坡体失稳条件的情况下，处理器发送三级报警信号。此外，在次声传感器和地震传感器同时监测到次声波信号和震动信号的情况下，处理器通过三级报警信号提醒关注。对于通过传感器获取的土体的深部位移和表部位移，在土体上可以设置图像采集设备，实时采集土体的视频图像，并与前期采集的基准图像进行比对，以修正土体的表部位移。结合深部位移、表部位移和实时计算的土体力学性能参数，以确定土体的面积和深度。处理器根据土体的体积与土体力学性能参数可以得到土体的质量参数和力学参数，并进一步建立土体与埋地管道的力学模型，在土体移动随时间变化曲线的的斜率发生显著变化或者土体对埋地管道的作用力能够造成埋地管道移动的情况下通过二级报警信号提醒进行警戒。
其中，力学模型的建立过程是通过测量土体、管道的位移、受力的动态过程，通过曲线拟合方法获得土体与管道相互作用的数值模型。力学模型的应用是用历史监测的数据，对未来监测数据的趋势进行预测。
进一步地，通过在埋地管道上设置多个管体位移传感器，处理器可以确定埋地管道上多个点的位移值。根据相邻两点之间埋地管道位移的相对值，处理器可以进一步判断埋地管道的宏观应变。在埋地管道上目标点的应变方向与宏观应变趋势一致的情况下，判断埋地管道形变均匀。在埋地管道上目标点的应变方向与宏观应变不一致，即宏观应变拉伸、局部应变压缩，或者宏观应变压缩、局部应变拉伸，则将目标点所在的截面定义为重要截面，且处理器可以确定该重要截面断裂的可能性较高，由此处理器在发送报警信号时可以将该重要截面的位置发送至显示设备。
此外，处理器可以根据埋地管道的应变变化率进行预警。处理器可以根据温度修正埋地管道的管道参数，管道参数包括管道应变。也就是说，温度应变消除是指处理器可以通过土体的温度来修正埋地管道的管道应变。在消除因温度产生的管道应变之后，处理器可以对埋地管道的管道应变进行微分，以得到应变速率，并对应变速率再进行微分，从而得到应变变化率。当应变变化率变化超过0.2则发送三级报警信号，提醒进行地灾治理；应变变化率超过0.5则发送二级报警信号，进行紧急处置；超过0.8则判断管体发生位移，应力出现集中，处理器通过发送一级报警信号给出临灾预警。
