Our company has been using the RIEGL VMX-250 since July 2010 in diverse scenarios, especially where data acquisition productivity is pertinent. In this presentation, we will be describing a long tunnel survey project. Spain has the longest high speed trail network in Europe. Recently, two parallel 25 km long tunnels were built and an accurate 3D survey was demanded by the Spanish authorities. A...

Purpose Tunnel construction using a tunnel boring machine (TBM) entails precise machine positioning and guidance in the underground space. In contrast to traditional laser-based machine guidance solutions, the proposed research aims to develop an automation alternative to facilitate TBMguidance and as-built tunnel alignment survey during tunnelling operations. Method A fully automated system is...

There are many mountains in the longitudinal center of Taiwan, which slow down transportation between the west and east in Taiwan. In order to solve this problem, Taiwan’s government decided to build a highway and an expressway between these two areas, which would include tunnels as part of the project because tunnels are more dangerous than the open road, how to safely enter, pass and leave tu...

The paper summarizes the Wisconsin Wind Tunnel Project’s research into parallel computer design and methods. Our principal design contributions—Cooperative Shared Memory and the Tempest Parallel Programming Substrate—seek to balance the programming benefits of a shared address space with facilities for low-level performance optimizations. The project has refined and compared a variety of ideas ...

Geology is the base for highways and tunnels construction. With the fast development of national highway construction, highway tunnel construction project are more and more complex. The completeness and accuracy are essential for the planning, design and construction of projects, while the ground information is quite poor in systematic, reliable and timely aspects. Therefore, the development of...

Purpose A community health center and clinic specializing in acupuncture partnered with a large managed care organization to determine whether acupuncture treatment might influence clinical outcomes and costs of care. Members of the managed care organization were referred through their physicians to receive up to 20 treatments for any of the following conditions: pain, headache, menstrual or me...

The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can...
