lpms

LPMS was developed from the highway maintenance practice of Guanxi and is characterizedby less data items, simple structure and practicability.

系统紧密结合广西公路管理的实际，具有数据项需求少，构造简单，实用性强等特点。

Compared with the existing high-order LPMs, the proposed LPMs are easier to extend to high orders, and their physical configurations are condensed and independent of the problem analyzed.

相比于现有的高阶集中参数模型，两类模型容易扩展到高阶，其物理结构简洁并与所分析的问题无关。

Moreover, due to the dynamic equations of LPMs with second-order derivative terms in time, the resulting structure-foundation-soil system can be solved by an explicit time-integration method.

此外，由于模型的动力方程具有二阶时间导数项，因而应用本文模型的结构—基础—土系统可以采用显式时间积分求解。
