Remedial shielding concepts for Line D and Line D facilities, Los Alamos Meson Physics Facility, Los Alamos National Laboratory, Los Alamos, New Mexico: Appendix 2. Final report
This appendix contains the structural embankment analysis of the following Line D tunnel sections: 6(T/21), 5(21/21), 3(21/21), 2(21/21), 1(21/21), 2(21/24), 6(T/21), 3(23/23), 5(21/21)S, and 5(2/8). The structural assessment is for each section being covered with a 30 ft tuff berm used as shielding in the event of a beam spill. Each tunnel section is subject to vertical and horizontal loads estimated as 115 lbs/ft{sup 2} for each 1 ft or overburden and horizontal loads equivalent to 0.2948 of the vertical load, due to the weight of the tuff berm placed over the structure. The profile of the berm is based on preliminary shielding assessments. Shear, axial and bending stresses are determined with the associated tunnel deformations.
