Deep Excavation In An Urban Area: A Case Study, Mohammad Sharif Rajabi, Farzin Kalantary
International Conference on Case Histories in Geotechnical Engineering
Due to regulations requiring provision of car park in the typical multi-story buildings in the urban areas and the high cost of land, deep excavation adjacent to existing structures have become common-place in Iran. Limiting lateral as well as vertical displacement of the adjacent structures has proven to be a major geotechnical challenge especially in the coarse grained alluvium of Tehran where determination of geotechnical parameters is tedious. Often active temporary support methods such as "rigid pad – anchoring" and/or "anchored soldier piles" are used in combination with nailing. However, arriving at the optimum design for such projects for the …

This paper will discuss the geotechnical aspects of foundation design, construction support, and the team work necessary to replace and upgrade 14 bridges along an existing, trafficked rail line through Central Illinois. Seven bridges were constructed using previously completed designs and seven bridges were constructed using a multi-disciplinary design-build approach. The geotechnical team provided construction support for the Phase I bridges while concurrently conducting geotechnical investigations and developing design criteria for the Phase II bridges. The project also involved many logistical considerations including minimizing bridge “out of service time” to less than ten hours for the construction of each bridge, …
Effects Of Arching On Measurement Of Embedded Pressure Cell In Embankment Dam, Dorsa Elmi, Ali Asghar Mirghasemi
Effects Of Arching On Measurement Of Embedded Pressure Cell In Embankment Dam, Dorsa Elmi, Ali Asghar Mirghasemi
International Conference on Case Histories in Geotechnical Engineering
Field observation and monitoring earth structures is vital to design the structure safely and efficiently. Among different types of instruments, earth pressure cells (EPCs) are used to measure soil pressure in embankment dams, which are not proved to be entirely satisfactory. Presence of cells and installation methods usually affect the accuracy of total stress measurements. Since earth pressure cells are prone to damage by large and sharp stones or by using heavy compaction rollers, one excavates a trench and place EPC within fine grained soil which is compacted with light-weight machines. This nonconformity results in local arching between the installation …

Rebuild Of Us 27, Don W. Dotson, Christopher J. Ramsey
International Conference on Case Histories in Geotechnical Engineering
An existing four lane section of US 27 was widened to eight lanes. The project lies in the rugged Valley and Ridge Province of the Appalachian mountains starting at the Tennessee River in Chattanooga, Tennessee and extending 2.6 km north to Signal Mountain Boulevard. This terrain presented many challenges to accommodate the road widening in the narrow, rugged topography. Multiple tiered wall systems consisting of large tieback walls, post-tensioned reaction blocks, and gravity MSE walls for a total of approximately 30 retaining walls were required. The retaining walls served to stabilize the thrust faulted geology while also minimizing right-of-way acquisitions. …

General Report – Session 2, Kenneth Gavin, Min-Keong Chung, Jose Clemente
International Conference on Case Histories in Geotechnical Engineering
The complete title of Session two on case histories of unexpected behavior of foundations made reference to unusual soils, diverse environments, a wide range of foundation test methods and structures ranging from historic monuments to tall buildings and towers. In attempting to provide a narrative to the myriad papers submitted which match the session themes we must consider whether unanticipated foundation behavior can ever be described as unexpected. In every project Geotechnical Engineers are charged with predicting the response of structures composed of or built on naturally heterogeneous material. The process (which is not linear) consists of many stages including …
