将岩土工程和测量数据组合用于监测

城市正在不断发展的实体，这些实体需要适应以满足人民的需求，维持经济职能并提供福祉和生活质量。在具有丰富文化遗产和城市旧城区的城市中，适应和建造新的基础设施构成了更大的挑战，因为任何建筑工程都必须保持历史建筑的完整性。

Crucial monitoring, including historic structures, is happening around the world without most of us noticing. Such is the case in Heidelberg, where at the heart of its Old Town a historic retaining wall built around 1871 is being monitored. To cope with the need to accommodate cars, an underground car park is being constructed right next to the historic retaining wall and foundation. The construction required to dig a10-metre-deep pit reinforced with bored piles在历史悠久的挡土墙的前面，用锚加强了。

对于位于内核河上的德国城市，这座挡土墙很重要，其历史性超出了其历史性价值 - 该结构限制了土壤以稳定斜坡。到确保其增强作用稳定，确保措施足够，并保留了历史墙壁，需要监视。

Integrating new buildings into existing old structures

TPI Vermessungsgesellschaft MBH（TPI）, an engineering company for surveying and geoinformation based in the Rhine-Main area in Germany, took the challenge of ensuring a new underground car parking beneath the existing old structure would保持其完整性。

“只要可以及时检测并在技术上测量任何损害，我们将发挥我们的作用，以防止损害。”外交说。TPI项目经理Dietmar Keizer。

为了检测墙壁上的任何倾斜，捕获3D中的任何位移并检测到墙上的任何沉降，TPI的量身定制监控解决方案包括：

• One Leica Geosystems total station TCRP 1201
• GeoMoS Monitor
• 现在的怪异！
• 13 Leica Gpr112棱镜
• 八轴的八个无线倾斜仪
• 一个流星传感器

Two different monitoring methods were set to guarantee independent checks. With a geodetic focus, the prism monitoring captures3D变形允许检测任何横向运动或墙壁沉降。A total station is continuously measuring five reference and eight monitoring points. With a geotechnical focus, two-axis inclinometers are检测墙倾斜。传感器连接在自我形成的网络网络中，每个节点都可以充当数据发送者和接收器。这样可以保证测量数据将以最快的方式到达网关，从将其上传到云并自动处理的位置地缘监测解决方案。

所有测量的数据，包括来自倾斜传感器的数据，角度和距离测量到棱镜和环境数据，例如温度和气压，automatically collected and analysed with GeoMoS。All acquired and processed data reported no tilt on the wall, hence, the reinforcements are good and stable enough and the team could proceed with the construction.

“GeoMoS Monitor and GeoMoS Now! are really sophisticated products that will certainly be further developed in specific areas. Thanks to the reliable support by our contact at Leica Geosystems, the setup of the system was straightforward. The user guide of the program was also very good. Even now after about five months, I still receive tips and support for individual program functions,”said Keiser at TPI.

TPI engineers and surveyors used in the past Leica Geosystems total station, GNSS, levels, laser scanner and laser tracker equipment. This time the tailor-made monitoring systems is giving specialists the挖掘和建造地下的信心。在Leica Geosystems员工的合格支持下，安全可以存储和Web服务使TPI专家能够：

• 永久自动衡量无手动干预
• 超过限制时自动评估并触发消息
• 通过互联网不断监视结果
• 启用设计的利益相关者（例如客户）访问结果。

Keeping everyone and everything safe

Excavations in urban areas pose risks to the people, structures and buildings on the surroundings. Fully-operating and reliable monitoring systems are essential to衡量任何偏差，做出更明智，及时的决策，并减轻任何风险。

由Leica Geosystems的专家支持，TPI Set带有固体参考框架的不同监视方法that included additional reference points, toguarantee independent checks。为了探测到毫米的任何运动，专家可以在保留其文化遗产的同时升级市区。
