When transverse and longitudinal rigidities and stresses of the arch bridge structure are preferably satisfied, construction difficulties and construction risks of a main arch ring and an arch structure can be reduced, and engineering cost is greatly reduced. The large-span railway desk type concrete arch bridge structure comprises the main arch ring (1), a border pier (21), an arch beam (3), an arch column (4) and an arch support foundation (5), wherein arch feet on two sides of the border pier (21) and the main arch ring (1) are supported on the arch support foundation (5); the arch beam (3) is supported on the main arch ring (1) by the arch column (4). The main arch ring (1) is equal-height single-box and multi-chamber section box-like plate arch; the arch top of the main arch ring is an equal-width section (11); and arc foot parts close to two sides of the main arch ring are linear widened sections (12). The border pier (21) forms a border pier T structure (2) together with a T structure beam (22) fixedly connected with the top end of the border pier (21); and the arch beam (3) is a multi-span continuous beam.

The invention belongs to the technical field of physical instruments, and relates to an earthquake early warning system for buildings. A micro-acceleration sensor is fixed in a relevant position on a building; when the building shakes or vibrates, the micro-acceleration sensor also correspondingly shakes or vibrates, and acquired acceleration data of the acceleration sensor is converted into displacement data through a data acquisition terminal; and if the spread of longitudinal waves of earthquakes is monitored, the displacement data is sent to a monitoring master station or an earthquake alarm systems in other place in a text-message transmission way via GSM wireless networks, and then a sound-light alarm system is started. The earthquake early warning system has the advantages of small size, light weight, low cost, low power consumption, long life span, high reliability, wide dynamic range, fast response, convenience for installation and debugging, and the like, and can be established in main regions of China to construct a stereoscopic monitoring system for natural disasters.

The invention belongs to the field of connection systems for every two adjacent carriages of a railway vehicle and relates to a traveling device used between adjacent train bodies of a motor train unit and capable of reducing the floor height. The traveling device is a low-gravity-center compact common bogie of a brand new form. An oil damper of the traveling device is used for restraining relative rolling pendulum vibration between the top of a carriage A and the top of a carriage B. The two ends of a common connecting device are fixed to underframe end beams of the two adjacent carriages respectively. Four air spring installation positions arranged on two sides are uniquely arranged on a common framework so as to contain sleeper beam middle through grooves. Under the condition that the existing fixed distance of each carriage of the motor train unit is kept unchanged, the traveling device can reduce the total number of bogies of the motor train unit and reduce the manufacturing cost of the motor train unit; moreover, while the un-obstruction performance of the interior floor of the motor train unit is improved, the overall gravity center and the floor height of the motor train unit are lowered, and passengers can conveniently get on or off the motor train unit. In addition, the traveling device remarkably improves the bend curve passage capacity and the turning maneuvering performance of the motor train unit.

The invention discloses a method for controlling settlement by horizontally drilling at embankment and injecting a light weight replacing material under the normal traffic circumstance, which is characterized in that: the slope embankment on one side or two sides of roadbed is drilled transversely by a drilling or chiseling pore-forming technique, holes lean a certain angle downwards so as to inject the light weight material; and the light weight material is injected into the holes, and then is solidified in the holes to form the light weight replacing material. A sleeve is also placed into the holes firstly, and then the light weight material or a non-backfill material is injected into the sleeve, so that pore-forming quality is ensured and the diffusion of the light weight material is avoided. The road does not need to be sealed, a pavement structure layer and an upper accessory structure cannot be damaged, and the normal traffic cannot be influenced.
